Dr. Greg is consistently a pleasure to visit. She’s always on top of all our concerns and never fails to catch even the slightest problem during our children’s exams. With our first born, we went through at least 5 other doctors and no one felt as competent and sharp and Dr. Gregg. Also, not only is she professional but most importantly there is a humanistic side to her.

Dr. Gregg was taking her time explaining everything and ask me if I had any other questions.
