A Statement from Dr. Chinitiz

I have had the privilege of working at Mt KiscoMedGroup/CareMount since 1984, and I was the first gastroenterologist in the group at that time. We now have many gastroenterologists spread out in various offices of our CareMount organization, with several endoscopy suites. We have links to GI and liver specialists all over the NY metropolitan area and Mass General Hospital.

I pride myself in providing GI tertiary care service in a community setting. As an associate professor of clinical gastroenterology at Montefiore Hospital, I also teach and lecture to the gastroenterology department there at various times throughout the year. This teaching gives me the challenge to keep my intellectual GI knowledge and skills as up to date as possible. Not only do I love teaching physicians ( I run a faculty lecture series at CareMount also) but I love teaching patients about all aspects of the field of gastroenterology. One of my goals of patient care is to educate the patient as much as possible so the patients can understand their disease processes as best as possible and thereby make informed educated decisions.

I read current medical literature voraciously, and use that knowledge to treat people with all varieties of gastrointestinal and liver diseases. I am interested in all aspects of gastrointestinal and liver diseases, diagnoses and treatments. I perform many GI procedures, especially endoscopy of the upper GI tract and colon, including capsule endoscopy to look at the small intestine. I am fascinated by liver diseases, and enjoy the detective work in deciphering the causes and treatments of abnormal liver enzymes, especially hepatitis B and C. With colonoscopy we save many lives by removing polyps that will cause colon cancer. Inflammatory bowel diseases of Crohn’s and ulcerative colitis may be the most challenging of all the GI fields, and they are also a very special interest of mine. Being a general internist also, I realize that patients are never just a colon or pancreas or liver, but each patient is unique and requires individual care.
I feel blessed to work in a multispecialty group that shares expert doctors in multiple fields, and shares an electronic medical record system enabling the doctors and patients to collaborate together on patient care plans.

Dr. Chinitz continues to have excellent performance on his quality measures of adenoma surveillance interval, colonoscopy screening interval, and adenoma detection rate. Dr. Chinitz has an interest and expertise in Inflammatory Bowel Disease.
