Welcome to the California Center for Functional Medicine.

Helping More People Prevent and Reverse Chronic Illness

Thousands of people have experienced Chris Kresser’s unique approach to diagnosing and reversing the underlying causes of chronic conditions. But, as a lone practitioner Chris could not meet the growing demand and faced an ever longer waiting list.

Chris partnered with Dr. Sunjya Schweig to form the California Center for Functional Medicine. They quickly hired a third clinician, Dr. Amy Nett, whom Chris specifically trained in his method. They recently hired Dr. Ramzi Asfour, an infectious disease specialist practicing functional medicine, and are in the process of hiring a nurse practitioner and a health coach to add additional layers of support for their patients.


Accelerate your healing with Chris Kresser’s unique approach.

Amy Nett, M.D., Kresser Staff Clinician

Amy NettAmy Nett, M.D., graduated from Georgetown University School of Medicine. She continued her medical training with an internship in internal medicine at Santa Barbara Cottage Hospital and a residency in radiology at Stanford University Medical Center. She became board certified in diagnostic radiology and then completed additional specialty training in pediatric radiology. Prior to attending Georgetown, she received her undergraduate degree in pharmacology from U.C. Santa Barbara and then spent two years dedicated to pursuing medical research. Dr. Nett began studying functional medicine after becoming frustrated with the conventional medical model in diagnosing and treating some of her own health issues. This experience brought to light the importance of diet and lifestyle, as well as the need for a more holistic and integrated approach to support health and wellbeing.

She began training with Chris Kresser in June of 2014 and started treating patients with a functional medicine approach later that year. She blends her conventional medical training with a functional medicine approach to provide individualized patient care. She recommends nutritional therapy, meditation, stress management, herbal and nutrient supplements, along with prescription medications, including bio-identical hormone replacement therapy (BHRT), to help patients achieve deep and lasting healing.

Dr. Nett is an instructor with the Kresser Institute ADAPT clinician training course, while continuing her own studies in functional and environmental medicine as a member of the American Academy of Environmental Medicine. She is also enrolled in the Institute for Functional Medicine (IFM) certification process.

Chris Kresser, L. Ac.

Chris KresserChris Kresser, M.S., L.Ac. is a globally recognized leader in the fields of ancestral health, Paleo nutrition, and functional and integrative medicine. He is the creator of ChrisKresser.com, one of the top 25 natural health sites in the world, and the author of the New York Times best seller, The Paleo Cure.

Chris has been studying, practicing, and teaching alternative medicine for more than fifteen years. He did his undergraduate work at UC Berkeley, and studied Chinese and integrative medicine at the Acupuncture & Integrative Medicine College, also in Berkeley. He has trained with world-renowned healers and educators in a variety of disciplines throughout the U.S., Thailand, and Indonesia.

Chris teaches and practices functional medicine, a personalized approach to health care that recognizes the biological uniqueness of each patient. In contrast to conventional care, which is almost entirely focused on suppressing symptoms, functional medicine eliminates symptoms by addressing the underlying cause of a problem. It is an evidence-based field of health care that views the body as an interconnected whole, and recognizes the importance of these connections in health and disease.
