Thanks and gratitude to Dr. John Sherman!  The improvement of my health and well being, as well as my wife, is nothing short of a MIRACLE since my visit with Dr. Sherman at the Tahoma Clinic.   I was badly wounded in Viet Nam leaving me with severe insomnia.  Now I sleep through the night in a deep sleep.  Before seeing Dr. Sherman I was in great pain in all my joints:  knees, hips, left shoulder, right arm and right leg.  I had extreme difficulty getting out of bed in the mornings.  To my amazement I now spring out of bed in the morning!!!  PAIN FREE!!!

For many years I had prostate trouble.  Dr. Sherman gave me some simple exercises, and a simple non-prescription juice to drink and my prostate is fine now.  I could go on but the list of my health and life improvements are great.  All I can say about my wife is that her life long list of allergies is gone and she is experiencing good health for the first time, and high energy as well.

It is with great joy and gratitude that I write this letter.  Thank you, Dr. John Sherman.

In early 2009, as a healthy seventy year old man, I suddenly lost most of my hearing. I saw three Ear, Nose, and Throat doctors. One inserted tubes in both ears. That did not help. One called me an “enigma”. He said the hearing in the left ear was so bad a hearing aid would not help, and a hearing aid in the right hear would provide marginal benefit for a limited amount of time. The third doctor suggested I reduce my salt intake and switch from regular coffee to decaf. I was desperate. Without hearing, my entire quality of life would change. In 2010, research led us to the Tahoma Clinic, and aldosterone. After a consultation with Dr. Lauren Russel and a urine test, I started taking 125 mcg of aldosterone twice a day. Amazingly, after two weeks, I noticed an improvement in hearing. Three months later my hearing has improved immensely. While it was not perfect, I could function in most aspects of my life. My limitations were few, and trivial (e.g. watching a TV movie, road noise in a car, the pitch of some people’s voice, whispering). In mid 2012 I changed from two pills per day to alternating from one pill one day and two pills the next day. Some days I would forget the pills altogether (complacency). I noticed a decline in my hearing. After several months I went back to two pills per day, and my hearing improved. While hearing can be somewhat subjective to the person hard of hearing, my family members witnessed the improvement. In November, 2012, I had my yearly phone conversation with Dr. Russel. Dr. Russel remembered an amazing fact. During my first consultations with her my hearing was so bad that my wife had to carry on the phone conversation with Dr. Russel. During the latest consultation my hearing was so good that I carried on the entire half hour consultation, not once asking Dr. Russel to repeat herself or guessing at what she said. My hearing is not perfect and sometimes I have difficulty because of different factors. But from what it had been, it seems as if a miracle has been performed. If my hearing remained at this level for the rest of my life I would be so very thankful.

The Tahoma Clinic is the best clinic I have been to for my health. I had ongoing UTI’s, psoriasis, postmenopausal issues etc. I called the clinic and they scheduled me with Dr. Cristina Persa. It was the best thing that has ever happened to me regarding my health. The staff, Dr. Persa, the laboratory, dispensary, and her medical assistant, Virginia, are all top-notch!

Dr. Wright did the right thing by providing his clinics to us. I am now UTI free, psoriasis is much milder (also working with findings from the book, “Healing Psoriasis” by John Pagano), and my postmenopausal issues are being resolved.

The most beneficial thing that has helped my health, my energy, my mood and my life was being tested for hormones and finding the right Bio-Identical hormone balance for my body. Dr. Persa is excellent at that. I am happy, health and have a more vibrant life than ever. I didn’t know I could feel this good at 55 years old. Thank you, Tahoma Clinic, for all you do and have done for me. I feel cared for and well taken care of.


Bellevue, Washington, Patient of Dr. Cristina Persa

I have been a patient of Dr. Wright’s for over 10 years and with each visit I am amazed at his intellect and research of all the latest medical and pharmaceutical data. Dr. Wright’s thorough patient testing and prescriptive recommendations, of vitamins, supplements, hormone replacement therapy gives total natural chemical balance to my system.


Recently I was in the clinic and the woman next to me stated how Dr. Wright had reversed her Macular Degeneration. This woman had been blind to the point she could not drive before treatment. That day she had driven from one of the islands, drove onto the ferry for her clinic visit and returned the same day. Her sight had been restored with Dr. Wright’s treatments. I was stunned.

Dr. Jonathan Wright’s research and development of the Bio-Identical Hormones (not “Premarin”/horses urine) is beyond reproach. My menopausal symptoms vanished and I feel younger and far more vibrant than my 66 years. It’s amazing to think that Dr. Wright actually developed, along with a pharmacist, a safe and effective hormone replacement for aging men and women, which is biologically identical to our own hormones. In addition, I am taking vitamin and mineral supplements daily which are pertinent and critical to my body’s chemical balances. These balances were evaluated thorough patient test findings from Meridian Valley Lab.

At my urging, our legal assistant drove the distance to the Tahoma Clinic, got tested and received the Bio-Identical Hormone Replacement prescription, specifically designed for her, and within one month her symptoms disappeared.

Pure and simple, Dr. Wright and the Tahoma Clinic save lives and increase the quality of living.

To Dr. John Sherman and the Tahoma Clinic:


Over the years my health had been on a steady decline. Though I have been a most energetic man my entire life, my initiative and drive were very much gone. I hurt all over and had a great deal of difficulty breathing. My medical doctor had numerous tests performed, including checking my heart, lungs and evaluating me for asthma, all of which turned up negative.

Finally, some friends told me of folks they knew who had been to the Tahoma Clinic with good results. I made an appointment and had the pleasure of being introduced to Dr. John Sherman.

When I did make the trip to Washington for my appointment I found Dr. Sherman to be well prepared and exceptionally knowledgeable. Unlike the many naturopaths from whom I had previously sought care, his approach was quite scientific. Dr. Sherman had several vitamin injections administered while I was still in the Seattle area. These injections were formulated for what my paper and blood work had shown my system to be lacking. With these I immediately experienced a slight bounce toward feeling better. Also, Dr. Sherman set forth a protocol of vitamins and minerals as well as enzymes to get my health back on track. His testing provided an extensive list of foods, rating each as to how well my body reacted to them. In this list I found many common things that I was eating every day were creating a strong negative reaction in my body. These reactions would include, but not be limited to, shortness of breath, restriction of the bronchial airways and a throbbing in the area of the esophagus that felt like my heart was throbbing.

Because of a lengthy history of damage I did not expect a miracle. On the other hand, I do feel much better and now have a choice regarding how I wish to spend each day since I can proceed as one who is informed. If I stay within the guidelines of the acceptable foods and work with indicated supplements I can continue to feel quite well. If I wish to behave outside of these parameters I end up taking the consequences.

Dr. Sherman and Tahoma Clinic have made a marked improvement in my life and how I feel from day-to-day. I highly recommend the knowledge and the professionalism of Dr. Sherman and the services provided at Tahoma Clinic to anyone who is in search of better health and not finding adequate results through other means. Over the previous 12 to 15 years I had spent several tens of thousands of dollars on various forms of naturopathic care–all with limited or minimal results. Tahoma Clinic is not inexpensive but assuredly on par, cost wise, with other clinics who offer much less. On the other hand, the return on investment has been well worth every penny spent. Dr. Sherman and Tahoma Clinic gave me a path to a new freedom in my life that I had sought for so many years. I am so thankful that caring friends brought me the information about Tahoma Clinic whereby I was directed to the capable care of Dr. Sherman.

Just a quick note of thanks to two of your staff members who are amazing to work with.


First, Dr. Angela Sadlon, whom I first visited with 3 weeks ago after having been a patient at Longevity Clinic for the last year. Among the many things we discussed, she introduced me to the Paleo diet and PACE exercise program. I found her to be extremely interested in my personal situation, an excellent listener, and pragmatic about changes for my lifestyle, which includes a great deal of business travel. On my second visit 9 days later, I had lost 6 pounds from taking her advice with the Paleo diet and PACE program!

The quality of her care and recommendations are far better than what I had received at Longevity, at far less the cost. I was so pleased that I brought my wife in this week to meet with her and she was equally thrilled.

I also wanted to compliment Rama, Medical Assistant. She is personable, caring, and extremely thoughtful. She went out of her way to help me obtain my supplements when I was consulting at the North Seattle location, saving me time and energy.

I was drawn to your clinic after reading “Bursting with Energy” by Dr. Shallenberger, and the forward written by you in that book; I feel fortunate to have access to such great, naturopathic medicine here in the Seattle area, and the outstanding staff that you have hired.


Camano Island, WA, Patient of Dr. Angela Sadlon

I initially called Tahoma Clinic because I had problems with migraines, joint pain, and fatigue.  I called and was given an appointment with Dr. Persa.  I am so thankful for that, as she has changed my life.  I am 43 and have always been active and in good shape.  The last 5 or so years I have been dealing with issues that caused me to feel fatigue, drained, chronic headaches, etc.  My quality of life had diminished.  Dr. Persa took her time with me listening to my issues and ordered different types of blood-work based on our conversation and within weeks of starting my prescribed medicines and supplements I began to feel better.  More energy, less intense and frequent headaches and less joint pain.  I am so ever thankful to have met her and the great staff (especially Virginia) at the clinic.  I has truly changed my life and I feel so grateful that each new day I can take full advantage of it because I feel well.  Dr. Persa has taught me a lot about cellular inflammation, the damage it does and how to treat and prevent it.  They are pioneers in their field.

I just wanted to say “thank you” for such a nice office visit yesterday. I am very impressed with you, Katy, the clinic in general, and the pharmacy. I really appreciated how much time you spent with me, learning about how to address my concerns – such a breath of fresh air after going to MDs for the past 2 years! I learned a lot from you in just one visit! Anyway, I’m glad I found you and look forward to working with you towards optimal well-being!


Seattle, WA, Patient of Dr. Russel

Dr. Sherman,


You have made such a difference in my life, it’s crazy! For the last 3 years, I have felt like my happiness, sanity, and joy have been slipping away—I felt like I was slipping away. My doctors tried to prescribe drugs, but I knew I needed some other kind of help, so I sought out Tahoma Clinic. Seeing you, Dr. Sherman—it has all changed for me! I’m so thankful for all the awesome “natural healing” products that are there to help us, but they wouldn’t mean a thing without someone like you to create the master plan. You seriously brought me back to that happy place I once called my life. While I do know that dark days come, they’re a part of life, it is now so much easier to “kick out the darkness”. You’re such a part of the light in my life! Thank you again for everything!


Olympia, Washington, Patient of Dr. John Sherman

My wife and I want to thank all of you for the time spent at Tahoma Clinic. The results, after two months, were thrilling. She can now see clearly out of both her eyes. The Macular Degeneration has been stopped and reversed subject to taking her pills regularly.


PS: This experience has prompted both my wife and me to consider doing free seminars beginning next year. Most medical doctors seem to believe that macular degeneration is untreatable. Your research over the decades proves there is hope and the possibility of stopping and/or reversing M.D. We live in an area where lots of seniors have M.D.


Palm Springs, CA, Patient of Dr. Lauren Russel

After a second diagnosis with breast cancer, I decided to look into alternative medicine, instead of using patent medication, to reduce the risk of reoccurrence. Through reading and research I discovered The Tahoma Clinic and Dr. Sherman.


When I shared with Dr. Sherman that my oncologist was urging me to take tamoxifen, which was not an option for me, and that I wanted to look at my hormones to try to understand what could have caused a reoccurrence of the estrogen receptor positive cancer, he was extremely encouraging and supportive.
After the test results came back, we found that a few of my hormones (the estrogens specifically as well as a couple of others) were out of balance. When Dr. Sherman followed up with me to go over the results, he spent a great deal of time explaining each result thoroughly and patiently, and answered each and every one of my questions.
We are working together now to balance my hormones, and I say we, because Dr. Sherman allows me to take part in my health care. He listens very attentively to my questions and concerns and even allows me to make recommendations in terms of dosage with regard to some of the supplements and hormones I am on.

I feel I have gained more knowledge from the care I get under Dr. Sherman in a few short months than I have in all the years put together with my oncologist since the original diagnosis of breast cancer 9 years ago. Dr. Sherman takes time to educate me on the different nutrients and minerals necessary for breast health, and what I can do to balance my hormones with regard to my diet and nutrition just to name a few.

Before I found The Tahoma Clinic, I felt very alone like there was nowhere to turn because I knew that all western medicine had to offer me was nothing short of a band aid, i.e. tamoxifen, and I wanted answers and to try to understand how this could have happened in the first place but also for a second time. When I posed questions to my oncologist she became frustrated with me and told she wasn’t sure what I was looking for but I would never find the answers.

After speaking with Dr. Sherman the first time, I started to feel the darkest cloud of depression begin to lift, severe anxiety start to calm, and for the first time in many months a feeling of hopefulness. To hear Dr. Sherman tell me that he can see how dedicated I am to the choice I have made to go alternative with my healthcare and that he can see I have the drive to really turn this health situation of mine around, does far more for me physically and emotionally than any pharmaceutical ever could.
I feel like I have a true advocate when it comes to my healthcare in Dr. Sherman. Every day I thank God for Dr. Sherman, Dr. Wright and the entire staff at The Tahoma Clinic.

I would like to thank Dr. Wright for introducing me to d-Mannose through his newsletter. This product has literally saved my life. I have Lupus and am subject to various infections all the time, and cystitis is one of the most frequent and most incapacitating. There was a time in my life when a trip to the doctor was on my to-do list every week! I had been given so many antibiotics that they no longer gave me any relief and I even developed allergies to most of them.


Ever since I have had d-Mannose in my cupboard, I haven’t had to call the doctor (not even once) for a bladder infection. I am eternally grateful. Please don’t ever discontinue this wonderful product.


Patient of Dr. Wright

Words cannot express how thankful and grateful I am that you are my “Miracle Doctor”.  I truly mean this.  After suffering several years after my diagnosis of fibromyalgia, and spending several months using a wheelchair and walker,  I am now free of those devices.  The regimen you have put me on is working.  I did not believe I could get better and you told me to “have hope” and that you were certain I would get better.  I cannot say I am 100% but I am 60%, if not more.  Just being able to walk on my own means the world to me.  Dr. Sherman is one of the most caring and knowledgeable physicians I have ever encountered.  I feel so blessed that Dr. Sherman is my Doctor!


Silver Springs, Nevada, Patient of Dr. John Sherman

My wife and I each have multiple medical problems.  Dr. Persa is sincerely committed to helping us.  In my case I was checked by four doctors including one specialist before coming to Dr. Persa.  I was told there was no cure and I must either be on prescription drugs lifelong, or have a surgical procedure annually.  I found out about Dr. Persa from my wife, and since I have been in her care my conditions have improved, and I am hopeful they will be cured.

Dr. Wright,


The advice you gave when I called your radio show on January 15, 2011 changed my life. I was miserable, thought perhaps I was dying, and now feel hopeful with a much appreciated, renewed sense of well-being and health. Thank you.

I asked what you could advise on pernicious anemia besides B12 injections. Your show was ending, but thankfully you had time to advise that I get tested for non-celiac gluten sensitivity. I immediately called the Tahoma Clinic North and saw Dr. Wendy Ellis the next Wednesday. The Enterolab test she ordered showed that my intestinal anti-gliadin IgA antibody was elevated. Under Dr. Ellis’ guidance, I have B12 injections more often and am on a gluten-free diet.

After more than 2 years of specialists who could not help me (endocrinologists, hematologists, cardiologists, etc.), I am no longer light-headed every day with constant nausea and body tremors.

Thank you and bless you, Dr. Wright.


Seattle, WA, Patient of Dr. Wendy Ellis

“I have been so proud and happy to have you as my primary care physician for about 20 years. I have spoken highly of you to all my friends and am so glad I can recommend you and your clinic…I continue to hear back glowing reports of you and your staff. So many of us with MS and our families have been mistreated by conventional medicine. You have a special role in our lives and hearts. Many of us are excited by the prospects of recovery. Bless you and your great work.”

“I’ve been coming to Tahoma Clinic since 1986. Dr. Wright has helped me and my husband more than any other doctor. I’ve been to lots over the years. I highly recommend Dr. Wright, he is the best and very good.”


Seattle, WA

I can’t say enough good about Tahoma Clinic.  I have been using their services since 1992.  Recently I was rushed to the ER in my home town of Chicago.  After four days in the ER I was diagnosed with having had a TIA.  The doctors didn’t suggest anything except to put me on a synthetic thyroid medication while I was in the hospital and suggested I continue using it.

Of course, I was not going to do any type of conventional treatment until I was able to talk to Dr. Persa.  She knew immediately what protocol I was to begin.  After seeing the test results and talking to me in-depth, Dr. Persa realized I had Grave’s Disease.  Within 10 days, the protocol she suggested improved my symptoms.  One month later, I was functioning better than I had in two years.  I have a better outlook on life, I am more energetic, my productivity has greatly improved and I am ecstatic about feeling good with minimal effort and without having my thyroid “burned-out”.

Tahoma Clinic is the alternative clinic.  Most others either do not know the answers or have learned from Dr. Wright.  I am grateful and thankful for their continued dedication to natural and alternative treatments.  Thank you, Dr. Persa and Tahoma Clinic.

“For over a decade, I’ve benefited from Tahoma Clinic’s emphasis on enhancing and maintaining wellness. Tahoma Clinic’s preventative approach to illness has helped keep me very healthy for all these years. I’m “younger” than before, due to the anti-aging regimen suggested by the Clinic. I especially like how the Clinic staff keeps itself apprised of all time-honored and emerging health approaches, so I can benefit from the best aspects of both conventional and alternative medicine.”


Seattle, WA

Dr. Russel, thank you so much for your kind and thoughtful clarifications following our recent appointment.  I so very much appreciate your knowledge and expertise; it is inspirational!  Especially rewarding to me is that you value my input on health matters and I feel like you really listen!!  I hold you in highest esteem for all you do!


Spokane, Washington, Patient of Dr. Russel

I want to say thanks to Dr. Cristina Persa and the Tahoma Clinic.  My daughter experienced significant hair loss and eventually was largely bald.  She was diagnosed with alopecia areata, an autoimmune disease in which hair is lost from some or all areas of the body.

We went to different doctors and specialists, experts in the field, who all advised there is no cure for alopecia areata.  They noted the hair loss can last for many years, it could worsen and the hair may re-grow on its own.  In my daughter’s case the hair loss was still worsening.  The specialists recommended the application of a topical steroid but advised there were side effects and that it may or may not work.  We instead decided to try the Tahoma Clinic.

We met with Dr. Persa at the Tahoma Clinic in Tukwila, Washington.  She was very prepared for our meeting, clearly up on all the latest literature on alopecia areata and confirmed there is no known cure, no silver bullet.  However, Dr. Persa advised she felt there were avenues that should be investigated but was upfront and honest about the chance of success and cautioned we should temper our expectations accordingly.  Dr. Persa carefully and thoroughly explained the areas she wanted to look at and why.  She explained her plan for the series of tests to be undertaken to try to narrow down possible causes – it was a very thorough and comprehensive clinical approach.

Following each series of tests Dr. Persa would meet with us to review the results, answer any questions we had and explain next steps.  Once she had the information she was looking for Dr. Persa then prepared a treatment plan that included dietary recommendations, mineral supplements and vitamins.  She reviewed the treatment plan with us to ensure we understood what was required and outlined when we needed to next meet.

It did not take long before we began to see positive results.  My daughter’s hair started to re-grow.  During the re-growth Dr. Persa met with us regularly to monitor the status, answer any questions we had and make adjustments to the treatment plan based on test results and her own observations.  Today, my daughter has a full head of hair and it continues to grow.

I cannot speak highly enough about the Tahoma Clinic and the staff, and Dr. Persa in particular.  Everyone at the clinic – administration staff, dispensary personnel, nurses, technicians and doctors – is extremely professional and goes the extra mile for their patients.  They were all extremely kind to my daughter during what was a trying and difficult period for her.  The Tahoma Clinic staff members are not working for the government or an insurance company; they are working for their patients and it shows.


Father of a patient of Dr. Persa

I am very grateful to Dr. Jonathan Wright for expert advice he has given me over the last 25 years to help cure my illnesses and protect and promote my health.
…After moving to Pakistan (1989) and Afghanistan (2005), I have visited Dr. Wright almost every two years, travelling 12,000 miles to see him to discuss medical conditions for which I had been diagnosed in other clinics.

I visited Dr. Wright first in May of 1987 when I felt I was having foggy thinking. He discovered that my stomach acid was very low (severe hypo-chlorhydria). He put me on Betaine HCl along with several other nutrients including Vitamin B12 and Folic Acid injections, L-Glutamine, Licorice and Zinc. In a few weeks, my thinking and energy improved, and subsequent measures over the years of my stomach acid in his lab also showed improvement.

…Having learned from Dr. Wright that low stomach acid can interfere with the absorption of 21 essential nutrients and having experienced these symptoms of low stomach acid, I am very grateful to Dr. Wright for discovering my problem with low acid production quite early.

Another important break-through in my health followed advice I received in September 2010 when I discussed with Dr Wright the muscle pain, sleep disturbances and weakening memory I was experiencing while taking the regimen of statin, beta-blocker and Propecia drugs that I had been prescribed by a cardiologist. Dr Wright ordered a number of laboratory tests and showed me the unfavorable biochemical changes that were observable, especially in hormones. He cited several studies that had shown the serious side effects of the above drugs. I chose to try several natural substances, dietary changes and exercise that I have been on since May of 2011. Gradually my muscle pain disappeared, my memory has definitely improved, my blood lipids are under control, and I have a great deal of energy for work and recreation. I sincerely thank Dr. Wright for his medical knowledge, and expert advice in taking care of my health.

Furthermore, what I have learned from Dr. Wright over the two and half decades of our doctor-patient relationship has helped me influence the health system of Afghanistan in the direction of a more holistic approach to disease prevention and treatment. Afghanistan now has rules and regulations for upgrading and promoting alternative medicine, and many people are making use of good diet, exercise, supplements and sunshine to protect and promote their health.

“…two health care providers and a vascular surgeon had told me that without immediate surgery I was going to lose my left leg within 3 months. That was 1-1/2 years ago…imagine my surprise the day that the “knot” in my leg let go and I could walk and even run a little without my leg giving out! It was a day that I’ll always remember. From the bottom of my heart, THANK YOU!”

“…the macular degeneration sounded like a sentence to blindness. I decided to take the I.V. treatments as I felt I had nothing to lose. By the ninth treatment, I felt that I could see better, objects were clearer and colors more brilliant. ..My eyes adjusted to the light much more quickly than before, television was easier to see and reading became easier. As an added bonus, I noticed that my hearing had improved some…I feel that the treatments have been very beneficial and worth the time and effort.”


Bainbridge Island, WA

I have been a patient of Dr. Wright’s for about 12 years. My grandson has Type I diabetes neuropathy in both legs from mid thigh to his toes. His pain level was 8-9 on a scale of 1-10. During a yearly check-up, I asked Dr. Wright if there was anything that could be done to help him. Dr. Wright gave me instruction to have him use Alpha Lipoic Acid, Benfotiamine and Vitamin D3 for 3 months and report back. By the end of 6 months, my grandson’s pain level had dropped to 1 or 2 and he was able to get rid of the pain medication. He is now going to college and getting all “A”s. Because of Dr. Wright’s help, he now has hope for his future. D.T.
