About Me
I am a seasoned physician with over 25 years’ experience in gastroenterology, hepatology, obesity medicine, and lifestyle medicine. Inspired by my father, a dedicated physician serving diverse communities in upstate New York, and my mother’s teachings of kindness and generosity, I have aspired to be a physician for as long as I can remember.
As a gastroenterologist, I am proficient in endoscopic procedures, including esophagogastroduodenoscopy (EGD) and colonoscopy. Among the gastrointestinal conditions I treat are gastroesophageal reflux disease (GERD), dysfunctional gastrointestinal disorders, irritable bowel syndrome, and liver conditions—fatty liver, viral hepatitis, abnormal liver tests, and others. I also focus on cancer prevention through screening, behavior modification and education.
My holistic approach to wellness integrates lifestyle modifications and preventive strategies to help patients achieve and maintain optimal health. My commitment to patient education and compassionate care has helped establish me as a trusted and respected figure in the medical community, and I also work to help educate future doctors as a clinical professor at NYU Grossman School of Medicine.
