Joseph Martz, MD, is chief of colorectal surgery and vice chairman of surgery at Lenox Hill Hospital, and chief of colorectal surgery for Northwell facilities in New York City boroughs and Westchester County. He has been practicing for more than 20 years and performs some of the highest volume of colorectal minimally invasive surgery, including sophisticated robotic procedures, in the tri-state area. 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. "It was exciting for me to see the remarkable change you can make in a patient's life with your hands," he says. He completed his residency at Mount Sinai Beth Israel and has worked in major hospital systems all across Manhattan. He's especially proud to be part of Northwell Health, which he joined in 2018. "Northwell is a special place where everyone makes a difference," says Dr. Martz. "It takes a team to provide the level of care that we want for our patients. We're really dedicated to making this a place where people feel at home." 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."
