Family and Friends

Involvement in medical care is the norm for my family.  My wife is a physician.  My two brothers are an optometrist and pharmacist.  My two sisters are a dietician and speech therapist.   Even my two best friends are physicians.  

Hobbies and Interests

I enjoy golf, fine dining, fine wines, classical music and travel. I have attended the San Francisco Symphony for the last 25 years. I am also an avid fan of the University of Southern California athletic department, especially the football program.

I also own a small farm in Kingsburg, California where I grew up.
