Services

Upper Endoscopy

Upper endoscopy gives physicians a direct, detailed view of the esophagus, stomach, and upper small intestine, making it one of the most reliable tools for diagnosing the source of abdominal pain, persistent nausea, or difficulty swallowing. It's significantly more precise than X-ray imaging when it comes to spotting inflammation, ulcers, and tumors, and it allows your doctor to take biopsies on the spot to rule out serious conditions. The procedure can also be used to treat narrowing, remove polyps, and manage active bleeding — all in a single visit.

Internal Hemorrhoidal Banding

Internal hemorrhoids can be uncomfortable to live with and even harder to bring up — but treatment doesn't have to be complicated. Using the CRH O'Regan Banding System, our internal hemorrhoidal banding procedure offers a non-surgical solution with a success rate above 99%. The entire process takes less than a minute, requires no prior bowel prep, and is performed right in the office. Most patients return to their normal routine the same day, with little to no downtime.

Colonoscopy Prep & Screening

A colonoscopy is one of the most important screenings you can schedule for long-term colon health, and proper preparation makes all the difference in getting a clear, accurate result. Our team provides detailed prep instructions well ahead of your procedure date, walking you through diet changes, prep solutions, and timing so you feel confident going in. During the exam itself, most patients experience only mild bloating or pressure, and the full visit — prep, procedure, and recovery — generally takes two to three hours.
