Our Functional Medicine Doctors and Clinicians
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 K. Schweig, M.D., is an expert in complex chronic illnesses which require rigorous investigation and management. He has been studying, teaching, and practicing integrative and functional medicine for over 20 years.
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.
Dr. Schweig continues to be active in medical education and has served as volunteer clinical faculty at the UCSF Santa Rosa Residency. He currently holds an adjunct faculty position at Touro University College of Osteopathic Medicine. Dr. Schweig has lectured nationally and internationally at conferences, hospitals, and universities.
Dr. Schweig has been in private practice since 2007, and is board certified in integrative and holistic medicine (ABIHM) and family practice (FAAFP). In 2014, Dr. Schweig launched the California Center for Functional Medicine (CCFM) with his friend and colleague, Chris Kresser, MS, LAc. CCFM is at the forefront of the functional medicine movement, offering patients a deep investigative approach to healthcare that is both high-touch and high-tech.
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 Functional and Integrative 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.
Ramzi Asfour, M.D. is board certified in Infectious Diseases and Internal Medicine. He graduated from New York Medical College then completed an Internal Medicine Residency Program at California Pacific Medical Center followed by a Fellowship in Infectious Diseases at UCSD. He has worked for the World Health Organization (WHO), Colombia University in South Africa, and The University of California, San Diego. Prior to attending medical school, Ramzi majored in genetics at UC Davis. He is currently Assistant Clinical Professor of Medicine at UCSF.
Ramzi’s interest in Functional Medicine was led by family health issues that were not resolved via the conventional approach, as well as his experience with his own patients in the US and abroad. His in-depth Functional Medicine approach, along with his more than 20 years of medical experience, offers the best of both worlds for his patients. Ramzi has completed the Institute of Functional Medicine’s certification program, as well as Chris Kresser’s ADAPT Level One Practitioner Training Program.
Ramzi brings an open mind together with a holistic, patient-centered approach to enable long-lasting recovery from chronic illness and optimal health. He uses diet, lifestyle interventions, parasympathetic system strengthening, investigative laboratory testing, supplements, herbs, and if necessary, prescription medications. Among other conditions, Ramzi is interested in auto-immune disorders, chronic infections (Lyme, tick-borne diseases in general, and other acquired infections), gut imbalances and disorders, detoxification, and mold and environmental illness. He understands how hard some of these conditions are to overcome and is prepared to partner with his patients who suffer from chronic conditions or those who seek to achieve and maintain optimal health.
Tracey O'Shea, Nurse Practitioner
Tracey O’Shea 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.

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.
