The Sharp Experience

I use the latest technology to provide high-quality care for my patients.



I feel extremely fortunate to work with talented oncologists and other medical colleagues to bring quality care to our patients. I am also grateful to have a collaborative partner in Sharp HealthCare, which has invested in amazing radiation technology that gives our patients the best possible chance of treating illnesses.

I am also proud to be affiliated with the Breast Health Center at Sharp Memorial Hospital, a nationally recognized, comprehensive breast health program that focuses on prevention, education, early detection and advanced treatment.

When I began practicing medicine, the senior partner in our group said I would never regret making San Diego my home, and he was right. My wife and I have raised our two daughters here, enjoying all that San Diego has to offer, and we can’t imagine living anywhere else.
