"The best possible health outcomes result from skillfully combining natural and standard medical therapies into a comprehensive healing program."


Conventional medicine is not equipped to properly treat complex, multisystem conditions. What is needed is a holistic approach that supports all the systems of your body. This approach is termed “Functional Medicine.” Functional Medicine addresses the underlying causes of disease, using a systems-oriented approach that engages both the patient and practitioner in a therapeutic partnership. It is an approach that has great advantages when treating a patient with a chronic medical condition.


During the past thirty years, I've helped the majority of my patients stabilize, improve, and restore themselves back to health utilizing natural healing methods (i.e. diet, supplements, hormone balancing, stress management, etc.) in conjunction with standard medications. Being on the front lines of the AIDS epidemic for over two decades helped teach me to value everything in my toolbox, including prescription medications. However, it's very important that medications be used skillfully and at the lowest dosages possible. Medications work best when they are combined with natural healing modalities.

I specialize in treating individuals with the following medical conditions:


  • Fibromyalgia

  • Mold Toxicity

  • Chronic fatigue

  • Recurrent infections

  • Hormone imbalances

  • Immune system disorders 

  • Gastrointestinal disorders

  • Neurodegenerative diseases

  • Multiple Chemical Sensitivity

  • Post-Covid Syndrome (Long Covid)

I’d be happy to speak with you by phone for 10-15 minutes to see if we’re a good fit. You can also send me a brief note and/or questions via the Contacts section of my website. I can consult with you either in person or by phone (or video) consultation.


If you would like to schedule an appointment, please click on the ‘Appointments’ tab. You will then be provided with new patient instructions. Thank You!

"I can confidently state that Dr. Kaiser is by far the best doctor I have ever encountered.  I have been in his care for over a decade and have gone from being severely ill (bedridden 24/7, unable to read, walk or care for myself) to now functioning at a high level.  Dr. Kaiser is an unlimited source of ideas, strategies, helpful tools and advice.  If you want to improve your health and the quality of your life, I strongly recommend you consult with Dr. Kaiser. Keep your hope alive! "
