P.D.
I really liked Christine Lee at OBGYN Partners for Health in Lafayette, but they only deliver at Alta Bates and I live two blocks away from John Muir, so I switched to OBGYN Specialists in Walnut Creek. What I liked about OBGYN Partners for Health is that it felt like a smaller practice and the office staff always seemed to have time to answer my questions over the phone and in person.
