Dr. Marquez diagnosed me with stage two colon cancer. She performed my surgery with a follow up with chemo therapy for six months. I was in the hospital Christmas and all through the New Year. She brought her family up to the hospital to meet and visit with me. I would have to admit she was one of the best doctors I have ever had. What a great spirit and bedside manners. I'd give her many stars and I would definitely recommend her to everyone. Thank you very much Dr. Marquez. DP

Dr. Marquez was wonderful with my son. He had never had any kind of surgery, but because of her excellent bedside manner & calm demeanor, he was not nervous at all. She did an excellent job with the wound & it has healed without any complications.

Highly Recommended!!! Definitely, without a doubt, the best dr/surgeon I've ever had in the 14 yrs that I've had Crohn's Disease. Very sympathetic and heart warming, which unfortunately is hard to find today when dealing with doctors. Nothing less than an A++++++
