I was born on the East Coast, in Massachusetts, and grew up in the Midwest, in Indianapolis, Indiana. As the daughter of a radiologist and a registered nurse, medical conversations were a familiar part of my life. As kids, my sister and I were intrigued by medical illustrations of childhood diseases that we found in one of my father's medical books. I am amazed to think that we now have vaccines to prevent many of these diseases!
I attended the University of Denver and Purdue University where I studied drama and sociology. Then I got married and moved to Houston with my husband. I wasn't satisfied with my previous studies, so I switched back to science and completed a degree in biology at the University of Houston. I then continued my studies at the graduate level in nutrition, intending to pursue a career in medicine. Finally, I got my medical degree and completed a pediatric residency at the University of Texas Medical School at Houston. I chose pediatrics because I liked working with children and was impressed by their ability to recover from serious illnesses quickly. I felt honored to be selected to remain at the university on the faculty for four years, where I supervised and taught residents in a nursery taking care of premature babies. The babies were cute, but I really missed the older children and working in an office, so I left the university and joined a group practice associated with Texas Children=s Hospital, where I stayed for six years.
I came to the Bay Area in 1999, because, once again, I followed my husband, who accepted a position as a dermatologist in Union City. It has been wonderful to explore the beautiful areas around the bay, and I don't miss the hot and humid summers in Texas one bit! After I came here I worked with several groups before I was able to come full time to Bayside. I am very happy to be joining Bayside, which is well known for its excellent patient care.
I am Board Certified in pediatrics. My greatest joy in pediatrics is to meet babies, toddlers, school children, and teenagers, and their families, and watch them all grow up and mature. I look forward to meeting all of you.
