I have to recommend my old docs when I was part of CPMC (I now have Kaiser, not by choice). For pediatrician, we used Dr. Stephen Rosenbaum, ###-###-####, 3838 Cal, Ste 111. I was in the hospital for 5 days before having c-section b/c I never dilated and every nurse on staff highly recommended Dr. Rosenbaum. He really takes his time with you and listens to you and the child and I really liked him. Because he takes his time with you, be prepared to wait a little longer for your appointments. His staff are awesome, too.
For OB/GYN, I would totally recommend Dr. Frederica Loftquist at 3838 Cal, Ste 103, ###-###-####. I switched to her when my original OB/GYN moved to the Peninsula to be closer to her new baby. Dr. Loftquist also has been voted the best OB, etc. in the Bay Area. Good luck!
