Primary Care


Dr. Humphrey has been a part of the San Ramon Valley since 1992. After graduating from UCLA/Ventura Family Medicine Program he worked in emergency medicine for 4 years before joining with Dr. Roberts in establishing Blackhawk Medical Group. Dr. Humphrey has cherished the practice of medicine and being a part of such a special community. His dream was always to practice medicine in a small town. He says, “The longer I live in this great valley, the smaller and more special it gets.”

Over the years Dr. Humphrey has found himself drawn to a more preventative and integrative style of medicine. He also increasingly enjoys more challenging and complex medical cases that present unique diagnostic or treatment dilemmas. Dr. Humphrey also loves the outdoors and celebrates it through hiking, surfing, hunting and fishing. His life goal is to both draw close to his creator and serve Him in his family, friends and community.
