My vision is that the patient always comes first. I strive to give outstanding and compassionate care to women in all phases of their lives. I still love to deliver babies, talk to people about their problems, to do surgeries as perfectly as I can and to try to find solutions for my patient’s health care issues. I always remember that everybody who comes to see me is doing me a favor and I really appreciate that fact.
