Dr. Sylvia A. Gisi M.D.


Dr. Sylvia A. Gisi M.D. began her medical career while finishing a post-graduate program at University of California of Davis. Upon completion of that program, she was selected to attend the University of Utah Medical School. After her first year, she was accepted to transfer to the University of Oklahoma to be near her husband.

Sylvia graduated in 1999 and was accepted for family practice residency training at Riverside County Regional Medical Center in Moreno Valley, California. Upon completion, she was invited to join a medical group in Temecula, California in 2002. After two years with the group, she decided to open a solo private practice.

Dr. Gisi specializes in women’s health, although she enjoys treating the entire family. She is very dedicated to her patients and looks forward to seeing them through their medical challenges. She believes in utilizing nutritional supplements as a first line therapy, while realizing certain medications can also be used effectively to treat many diseases. She is currently taking new patients and welcomes patients of all ages. Please call or stop by our new office for more information or to set up an appointment. We can be reached at (951) 303-6158
