Garrett M. Nash, MD, MPH, FACS, FASCRS - MSK Colorectal Surgeon

I am a medical oncologist who specializes in the treatment of patients with gastrointestinal cancers. My research interests focus on the development of new therapies. In particular, I am investigating innovative ways to use the immune system to treat cancer.

I am a medical oncologist whose research and clinical activities focus on treating patients with pancreatic and hepatobiliary malignancies. I work very closely with a team of surgeons, oncologists, and radiation therapists to determine and provide the best treatment for patients with these diseases.

I have been on the faculty of Memorial Sloan Kettering since 1989, and over the years I have treated thousands of people with common as well as rare gastrointestinal cancers. I have particular expertise in managing cancers of the colon and rectum, as well as rare tumors of the digestive tract such as carcinoid and pancreatic neuroendocrine tumors, and other digestive tract cancers such as liver, pancreas, stomach, and esophagus cancers. I also treat other neuroendocrine tumors such as adrenal cancers and pheochromocytomas.
