Dr. Kelly’s Approach
Where conventional medicine falls short in addressing chronic fatigue, autoimmune disease, or any other complex condition, taking a functional, integrative, and environmental viewpoint is often the best place to find the answers you’re looking for.

Functional Medicine
Functional Medicine is a style of medicine that seeks to identify the root cause of illness and remove the cause, allowing the natural healing capacity of the human body to flourish.
Functional medicine often incorporates an extensive variety of laboratory testing beyond what conventional laboratories can investigate.
It is an evolution of the practice of medicine that incorporates conventional tools and cutting edge science to better address the healthcare needs of today.
Integrative Medicine
Integrative Medicine utilizes a variety of healing modalities in the service of healing including but not limited to: allopathic/conventional medicine, pharmaceuticals and surgery, herbal medications, nutritional supplements, acupuncture, energy modalities, body work, Ayurvedic medicine, etc.
Functional and Integrative medicine practitioners are often one and the same.
They engage the patient in a therapeutic relationship and spend time listening to the patient’s stories, reviewing all the factors that can impact health and creating a personalized, comprehensive plan for healing.


Environmental Medicine
Environmental Medicine recognizes and addresses the impact of the external exposures a person may encounter thus resulting in disruption of bodily function on both small and large scales.
These exposures include chemicals, such as pesticides, phthalates, persistent organic pollutants, toxic metals, air pollution particles, as well as naturally occurring biological toxins such as mycotoxins.
These invade the body leading to dysfunctions in the immune system, neurological system, endocrine system and others. Environmental medicine practitioners, then work with the patient to support the removal of the chemicals and a restoration of function and wellbeing.
New research suggests that Mast Cell Activation issues may be behind some of your ongoing symptoms.

What People are Saying

I have had the privilege of working with Dr. Kelly McCann for many years now. She is one of the pioneers in the understanding and treatment of chronic inflammatory illness. I have consulted with her on many cases and find her to be both a personal and professional beacon.
Neil Nathan, MD, Physician and Author of Toxic: Heal Your Body, Mold and Mycotoxins and Energy Diagnosis.

In knowing and working closely with Dr. McCann these past many years, I know her to be a brilliant clinician who always goes the extra mile for her patients. She has a broad and deep working knowledge of medicine, both traditional and innovative functional medicine. She has been on the cutting edge of understanding the intersection of environmental toxin exposure, chronic infection, and complex disease for many years and as such, is a valuable resource for many doctors and is a guiding light for many patients. I am very blessed to have her as a colleague.
Lyn Patrick, ND, Physician educator, founder of Environmental Health Symposium and co-founder of emeiglobal.com

I’ve known Dr. McCann for several years now to provide excellent service to her patients with mast cell activation syndrome (MCAS). She has proven to be a leader in southern California, and even nationally, in educating her colleagues about this prevalent, if just recently recognized, disease. I expect patients with suspected or proven MCAS will find themselves “in good hands” with Dr. McCann’s care.
Lawrence Afrin, MD, Hematologist/Oncologist, Author of Never Bet Against Occam: Mast Cell Activation Disease and the Modern Epidemics of Chronic Illness and Medical Complexity.

I have known Dr. McCann for almost 10 years and have found her to be one of the most ethical, compassionate and knowledgeable physicians I know. She is a dedicated scholar who is always learning about the newest therapies available to help her patients. I know she cares deeply and will always do the best she can for her patients, using the best of conventional and integrative medicine. I have never seen a more thoughtful and organized physician who considers each patient as an individual, not just a problem. You know you are in capable hands when you work with Dr. McCann.
Darin Ingels, ND, FAAEM, FMAPS, Author of the Lyme Solution

I have known Dr Kelly McCann for over a decade and I feel she is one of the most well rounded and highly educated physicians in this country! Few can say they are board certified in internal medicine and also board certified in integrative and functional medicine. Plus she has a master’s degree in Spiritual Psychology. Having this knowledge base allows Dr McCann to integrate all aspects of patient care both traditional and non traditional. She practices what I believe is true healthcare which is healing not just the body, but also the mind and spirit.
