Jonathan V. Wright, MD

Medical Director

A Harvard University and University of Michigan graduate, Dr. Wright continues to be a forerunner in research and application of natural treatments for healthy aging and illness.

A Harvard University and University of Michigan graduate, Dr. Wright continues to be a forerunner in research and application of natural treatments for healthy aging and illness. Along with Alan Gaby, M.D., he has since 1976 accumulated a file of over 50,000 research papers about diet, vitamins, minerals, botanicals, and other natural substances from which he has developed non-patent medicine (non-“drug”) treatments for health problems.

Dr. Wright has taught natural biochemical medical treatments since 1983 to thousands of physicians in the USA, Europe, and Japan. He was the first to develop and introduce the use of comprehensive patterns of bio-identical hormones (including estrogens, progesterone, DHEA and testosterone) in 1982 and directed the development of tests to ensure their safe use at Meridian Valley Lab. He teaches use and laboratory monitoring of bio-identical hormones at several seminars each year.

He also originated successful natural treatment for elimination of childhood asthma, developed treatment to stop vision loss or improve vision in the majority of individuals with “dry” macular degeneration, was the first to use aldosterone to reverse age-related hearing loss, discovered the effect of iodine on estrogen metabolism and cobalt on steroid detoxification, popularized the use of D-mannose treatment for E. coli urinary tract infection, developed effective natural treatment for seborrheic dermatitis, allergic and viral conjunctivitis, and Osgood-Schlatter’s disease. In 2013, he resurrected forgotten research and treatment protocols for the application of Human Chorionic Gonadotropin (hCG) to treat severe neurological problems.

Dr. Wright founded the Tahoma Clinic (1973), Meridian Valley Laboratory (1976), and the Tahoma Clinic Foundation (1996). Tahoma Clinic was established to approach disease by natural means and emphasize correction of imbalances in the body that lead to disease. The infamous 1992 FDA Tahoma Clinic “raid” (“The Great B-Vitamin Bust”) was a major impetus for Congressional reform of vitamin/mineral regulation.

Dr. Wright continues to be an advocate for patient freedom of choice in healthcare. An acclaimed lecturer, Dr. Wright speaks nationwide on varied topics including nutritional medicine, natural hormone replacement therapies for men and women, the natural treatment of cardiovascular diseases, asthma, diabetes, the use of D-mannose for bladder infection, the health benefits of Vitamin D as well as many other topics.

I only use your test because it continues to be the most clinically correlative test available. Patients nearly always note symptoms from the positive results and have improved health from avoiding those foods.

Terra Sowinski, ND, Belfair, WA

The food panel results were delivered to me in a timely manner, and very easy to read and develop a game-plan for my future health benefits. While most medical professionals may suggest cumbersome food-elimination diets, or perhaps a scratch test designed for more extreme allergies, nothing compares to the information provided from the extensive food panel at Meridian Valley Lab. This report immediately showed me my food sensitivities which were easily eliminated from my diet; reducing inflammation and improving my overall digestive health without the guesswork. I’m only sorry I did not order this sooner.

Danielle Langlois, Duvall, WA

My 15 year old son had experienced fatigue and difficulty with mental focus for over 7 months and we were suspecting food allergies because some days he was better than others, and multiple trips to doctors hadn’t helped. We took him in to Meridian Valley lab (we live within driving distance, but you can order a mail testing kit if you live too far away to go there) and had the basic food allergy test done and now that we have him off the foods he was reacting to (we finally figured out that his Omega 3 supplement has egg yolk in it!) he now has his energy and concentration back. We are so pleased.

Kathy Demartini, Tacoma, WA

Very happy with the reaults of this new knowledge. My health has improved and I have lost weight since eliminating the foods that I was sensitive to.

Joy Williamson, Dallas, TX

Eye opening test for sure. Once I figured out my food sensitivities I revamped my diet and feel like a new person.

Michelle Lin, Salem, OR

I was having terrible breathing problems and after taking this test I found out I was regularly eating things that I was very allergic to. Once I stopped eating these my breathing problems went away. I also found out I wasn’t allergic to foods that I thought I was allergic to. This is a very helpful test and I recommend it.

Michael Davis, Minnetonka, MN

I have had three of these tests done over the course of three years. Eggs consistently show up in the red almost off the chart. I was suffering from disfiguring joint problems for 9 years and no doctor could help me. All they did was prescribe steroids and at one point they tried to get me on Raptiva. Fortunately I said no to the Raptiva. It was later taken off the market because it caused neurological damage. The Food Safe Allergy Test showed me the foods to avoid, especially eggs. I no longer have the joint problems! No drugs needed! This test should be the first diagnostic used by doctors and individuals if suffering from inflammation related diseases. I will get the test once a year for the rest of my life, as it provides the best advice to steer clear of damaging foods.

Stacy Redding, Tampa, FL

Meridian Valley Laboratory has been helping me with all of my laboratory testing needs for over 8 years. I especially like the food allergy panels and 24-hour urine hormone tests that they offer. I highly recommend Meridian Valley Laboratory as a trusted resource for naturopaths and other types of practitioners who are interested in the most modern testing options available anywhere.

David Zeoli, ND, Charlottesville, VI

We’ve had hundreds of patients benefit from the food sensitivity testing. Many patients who knew food was causing their symptoms but could never pinpoint exactly which foods, but also patients who didn’t realize food could be the cause of their symptoms. Patients are often impressed by the number of foods tested, foods they likely would not have considered to be possible suspects. As a provider, the specific nature of the test – breaking food groups down into specific foods – as well as the information displaying the severity of sensitivity is extremely valuable to identify exactly which foods are of greatest issue.

Shane McCall, DC, Peoria, AZ

I have been in practice since 2007 and every year more women come into my office seeking help with hormone balancing. Meridian Valley provides the most reliable and comprehensive hormone tests and I trust their results over other labs. The expert on-staff doctors help me to interpret the test results and determine the most appropriate form of treatment for each individual patient.

Sara Kinnon, ND, Vancouver, BC, Canada

I have been using Meridian Valley Laboratory for 30 plus years and their Food Allergy Test has been the cornerstone of my medical practice and has helped thousands of my patients achieve resolution of their chronic health problems.

Tris Trethart, MD, Edmonton, AB, Canada

Meridian Valley Labs has been my choice for hormone testing for over 10 years now. Their comprehensive analysis with my patient’s results has proven consistent time and time again. The labs are highly sensitive while offering clinically effective testing tools which provide insight into each patient’s unique symptom picture.As a Naturopathic Doctor, who has been helping address hormone imbalances for years, I highly recommend Meridian Valley Labs for their simple, non-invasive, and accurate methods to assess bioavailable hormone levels.

Nirvana Tehranian, ND, Newport Beach, CA

As an integrative MD, I am accustomed to doing in-depth lab testing and focusing on the preventative and proactive aspect of healthcare. I tell my patients that diet, exercise and a healthy gut is the foundation for wellness, on the mental and physical levels. Foods we eat can trigger numerous medical disease processes, especially inflammation, anxiety, and autoimmune conditions. Patients are sick and tired of feeling tired and sick and are focused on healing from within. The Food Intolerance test by Meridian Valley is a crucial part of lab testing for my patients. I have patients coming in and specifically requesting this test, because they know that foods they may be consuming are making them sick. My patients and I are very happy with the testing offered by Meridian Valley.

Deepa Verma, MD, Clearwater, FL

I have been practicing Clinical Nutrition/ Functional Medicine for over 20 years. For the past few years I have gravitated toward Meridian Valley Lab for more of my functional laboratory testing despite the numerous labs available in the industry now. I find their competitive patient pricing, customer service and depth of laboratory panels to be a leader in the field. I particularly find the IgG FoodSafe bloodspot testing extremely convenient and affordable for the patient. Thank you Meridian Lab for making my practice easier and more stress-free!

Lisa Fitzwilliams, DC, Carbondale, CO

I have been working with Meridian Valley labs for nearly 20 years.
