Procedures offered

Upper endoscopy (EGD)

Used to evaluate the esophagus, stomach, and upper small intestine when symptoms such as reflux, swallowing difficulty, or upper abdominal pain need further assessment.

Colonoscopy

Used to evaluate the colon for symptoms such as changes in bowel habits, bleeding, or abdominal pain, and to support screening and follow-up when clinically indicated.

Capsule endoscopy

Allows visualization of the small intestine when additional information is needed beyond standard endoscopy or colonoscopy.

Bravo™ pH Testing

A wireless pH monitoring study used to measure acid exposure over time, helping guide evaluation and management of reflux symptoms.

Esophageal manometry

Evaluates how the muscles and nerves of the esophagus function during swallowing, helping guide care for swallowing or motility-related concerns.

Anorectal manometry

Assesses pelvic floor and rectal muscle coordination, supporting targeted treatment for chronic constipation, difficult bowel movements, or fecal incontinence.

Hemorrhoid Banding

We offer in-office hemorrhoid banding as a safe and effective treatment option. This approach relieves symptoms safely and effectively, without surgery or hospitalization.

In-office Testing

H. pylori Breath Test

A non-invasive test used to detect Helicobacter pylori infection, which can contribute to ulcers and chronic stomach symptoms.

SIBO Breath Test

Used to evaluate for small intestinal bacterial overgrowth in patients with persistent bloating, gas, or unexplained digestive symptoms.

FibroScan®

When appropriate, we offer in-office FibroScan® testing to assess liver stiffness and fat content in patients with fatty liver disease. This non-invasive, ultrasound-based study helps evaluate liver scarring (fibrosis) and fatty changes, often without the need for a biopsy.
