Why did you choose to specialize in Gastroenterology?

I choose to specialize in gastroenterology because of the ability to make a real difference in patients lives. The field is advancing rapidly and being able to offer new technology and treatments improves the care for our patients. Building strong relationships with patients and their families is the best part of the field.

Do you have a specialty of interest within GI?

I specialize in all aspects of general gastroenterology and hepatology as well as endoscopy. I have received additional training during my fellowship in the management of inflammatory bowel disease (IBD) and endoscopic resection of large polyps such as endoscopic mucosal resection (EMR).

Some areas of interest I treat include:
Ulcerative colitis, Crohn’s Disease
Colon cancer prevention and screening with colonoscopy
Acid reflux or GERD
Diseases of the liver
Irritable bowel syndrome
Gastrointestinal bleeding and anemia
