Screening colonoscopy

The only screening test that both finds and removes precancerous polyps. Recommended from age 45 and covered as preventive care by most plans.

Upper endoscopy (EGD)

For heartburn that won't settle, trouble swallowing, ulcers, celiac disease and unexplained stomach pain. About ten minutes, with biopsy if needed.

FibroScan liver assessment

A painless ten-minute scan that measures liver fat and stiffness. No needles, no sedation, results the same visit.

Polyp removal & biopsy

Polyps are removed during the same colonoscopy. We call you with pathology results and explain what they mean.

Flexible sigmoidoscopy

A shorter look at the lower colon for bleeding, pain or a change in bowel habits, often without sedation.

Hemorrhoid treatment

Office-based treatment for internal hemorrhoids, usually without surgery or downtime.

Conditions we treat
