About Dawn Marie De Castro-Marceau, MD

When I was a premedical student at UC Berkeley, I did an observership with a local internal medicine physician. I decided to become a physician based on this experience because I was impressed with the unique, trusting and long-term relationship that that doctor and his patients shared. I believe in making sure that patients play an active role in their own health care. Patients should be educated fully about their conditions and their management options, and consider these choices along with my medical recommendations in making their decisions. In my spare time, I enjoy having an active lifestyle and going hiking with my husband and our goldendoodle puppy, who seems to have boundless energy.
