A born and bred New Yorker, Dr. Martz spent his early days volunteering in an operating room, which helped him realize how much he wanted to become a surgeon.

This world-class team at Lenox Hill also includes nurse practitioners, physician assistants, social workers, specialists and nurse managers to help with every aspect of care.The exceptional skill and experience Dr. Martz offers is for the full range of colorectal conditions-including diverticulitis, colon cancer and complex pelvic issues. In fact, the complexity of the cases he treats is what drives his passion for medicine. "After years of training, I'm happy to be able to provide the skill to treat these difficult problems," he says. "Seeing the patients' outcomes-seeing them do well-becomes more meaningful for me every time."The positive patient outcomes achieved through minimally invasive surgery, which include less pain and shorter hospital stays, keep Dr. Martz focused on the future of colorectal care. He's dedicated to educating new physicians on minimally invasive and robotic procedures, getting involved in promising medical device studies, and looking to technology to continually improve treatments."Getting patients healthy is what's truly important to me," says Dr. Martz. "I treat every patient as if they are part of my family. I am completely committed to their care."
