When I was pregnant, my doctor went on maternity leave and I then went to her backup doctor, Dr. Krishnan before getting a new OBGYN assigned Dr. Krishnan was overbooked already). Even before she was my doctor, I had to go to hospital for a day during my pregnancy and she was the doctor on call. Even though she didn't deliver my baby, she delivered my friend's and she was happy.
She is very professional and corteus. Very knowledgable and make you feel confortable. She is good about returning calls and explains why she is recommending a test or a procedure.
Overall, we had good experience with her and would not hesitate in recommending her.
