"The exact type of doctor we needed. Dr. Kammerer really listened to what we were saying and truly cared about make us, as new parents, feel at ease. Also, our son loves her and never cried once. She was patient and encouraging when we were having breastfeeding trouble in the beginning. We couldn't recommend her more!!
