“I enjoy doing OB because it’s such a momentous occasion in a person’s life. Whether it’s the first baby or the last, it’s an opportunity to witness the miracles of one of God’s greatest gifts to us. It’s an honor to experience that with my patients and to help prepare them for one of their biggest, but most exciting challenges…parenthood!”
