About

Bio

I grew up in Wisconsin, and I attended Columbia University as an undergraduate. I completed medical school at Boston University, and went on to my radiation oncology specialty training at MD Anderson Cancer in Houston, TX. I was an Asst Professor at MD Anderson before moving to the Bay Area.

Specialties
Doctors may have more than one area of specialty interest. Board certification in a specialty area means the doctor has completed formal training and has practice experience in that specialty, and has passed the certification examination from the corresponding accredited medical specialty board.
