Our Team

The California Center for Functional Medicine was founded by two of the most respected thought leaders in the field of functional medicine, Dr. Sunjya Schweig and Chris Kresser, M.S., L.Ac. Our team of clinicians and staff has been hand-picked to provide the highest quality patient experience possible.


Sunjya Schweig

Dr. Schweig received his B.A, from the University of California, Berkeley.  He attended medical school at the University of California, Irvine, where he helped design and lead the complementary and alternative medicine (CAM) curriculum.  He served on the Board of the Susan Samueli Center for Complementary and Alternative medicine and was chosen as one of twenty medical students to attend the NIH Leadership Training Program in Complementary and Alternative Medicine. 

Dr. Schweig completed his family medicine residency at the University of California, San Francisco (UCSF), Family Practice Residency Program in Santa Rosa, CA.  During his residency he was instrumental in developing and founding the Integrative Medicine Fellowship program.

Chris Kresser

Chris Kresser

Chris 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, Your Personal Paleo Code (published in paperback as The Paleo Cure). Chris was recently named by Greatist.com as one of the 50 most influential people in health and fitness, along with Michelle Obama, Michael Pollan, Dr. Andrew Weil, Tim Ferriss, and Dr. Mercola—and his work is frequently cited in national publications such as Time, The Atlantic, and NPR, and on Dr. Oz and Fox & Friends, where he has appeared as a guest.

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 works with patients from a functional medicine perspective. He uses lab testing and a thorough intake process to discover the underlying causes of disease, and a combination of diet, supplements, botanicals, and lifestyle change to address them. His work is deeply informed by his own decade-long struggle with a chronic, mysterious disease—which he later recovered from through his own research and experimentation. Chris lives in Berkeley, CA with his wife and daughter.

Associate Clinicians

Amy Nett

Amy Nett

Amy 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 through 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 courses, 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.

Ramzi Asfour

Ramzi Asfour, M.D. is a Marin County local. From his earliest childhood memories, he felt a strong calling to study medicine and to help others. As part of his intensive medical studies, he did his residency in Internal Medicine at the California Pacific Medical Center, where he was chosen as Resident of the Year. These experiences also won him a Fellowship in Infectious Diseases (ID) at the University of California, San Diego.

As you might imagine, specialists in Infectious Disease are in very high demand around the world right now. Dr. Asfour was honored to bring his skills and training to patients in need in countries such as South Africa, Ethiopia and Guatemala, and to have worked with the World Health Organization. One of the most startling facts that he observed in the developing world was a much lower incidence of Autoimmune Disease, IBS and related illnesses. In that respect, they were healthier than the people that he knew back home. This was, so to speak, food for thought, and from this observation, and his own personal journey, his interest in functional medicine began to emerge. He could clearly see that there were a variety of different approaches to healing and that these bodies of knowledge had never been adequately investigated by practitioners of conventional medicine.

When Dr. Asfour returned home, he practiced conventional medicine with a focus in Infectious Diseases, but soon came to the realization that he could do much more for his patients using a more in depth approach. He joined the Institute of Functional Medicine (IFM) and had the good fortune to meet and work with Dr. Sunjya Schweig, who has supported him in his journey.  He is committed to helping his patients through an entirely original combination of conventional and functional medical practices.

Tracey Clow

Tracey Clow is a licensed Family Nurse Practitioner (FNP-C) who graduated from Samuel Merritt University with a Master’s degree in Nursing. She became board certified through the American Association of Nurse Practitioners and was first introduced to Functional Medicine in 2013, when she began her journey through the Institute for Functional Medicine’s certification program. She has trained with the Kresser Institute (ADAPT) program and is an IFM Certified Practitioner.

Tracey chose to become a nurse practitioner because it provided her the opportunity to help patients gain control of their health and become active participants in life. Seeing people enjoy every aspect of their health is rewarding. Studying and practicing functional medicine has given her additional tools to ensure that patients get the individualized, comprehensive treatment they deserve.

Tracey finds that communication is key for all successful and sustainable relationships. She tries to emphasize this with her patients during the first encounter, so that they understand what makes functional medicine different than conventional medicine. She listens carefully to the patient, especially as they discuss their needs and how they fit into a comprehensive, individualized health plan. Tracey hopes that she gives her patients motivation to live healthier, more fulfilling lives. Her goal is to help them understand the pivotal role they themselves play in designing and carrying out their treatment plan for health optimization.  She is grateful for the opportunity to work with the California Center for Functional Medicine and is honored to be part of this journey.

She was thrilled with the results functional medicine had in her own life, and recognized the potential benefits of using this approach with her future patients.

Lisa has trained with the Institute for Functional Medicine (IFM) and the Kresser Institute (ADAPT). Her training included a functional medicine approach to gastrointestinal dysfunction, immune dysregulation, hormonal imbalance, cardiometabolic syndrome, stress management, toxins, food sensitivities and nutritional therapy.
