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. Dr. Ramzi Asfour, an infectious disease specialist practicing functional medicine, joined CCFM in April 2016. Tracey O’Shea, our nurse practitioner, and Danielle Cook-Kawash, our nutritionist and health coach, began helping our patients in early 2017.

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 Institute of Functional Medicine Certified practitioner and currently a fellow in the Academy of Integrative Health and Medicine (AIHM). She is also an instructor with the Kresser Institute ADAPT clinician training course.
