We are a boutique alternative medical practice focused on complex or serious health issues including cancer, fertility, autoimmune, neurodegenerative, and other refractory medical problems. The practice was founded in 1997 by Dr. Raymond Chang, who currently serves as Medical Director of the clinic, and clinical services are provided by a core of expert practitioners. The clinic is an affiliate of the 501(c)(3) non-profit Institute of East-West Medicine which is advised by a distinguished Board of senior physicians and researchers.

We emphasize an unconventional approach to conditions refractory or poorly responsive to standard cookie-cutter medicine. Contrary to the current trend of protocol based “cafeteria” treatments, we offer a broad range of repurposed, investigational and alternate therapies and truly consider each patient individually to tailor personal healing programs blending conventional and alternative, Eastern as well as Western approaches with the patient’s optimal health and recovery in mind.
