Every Procedure, Handled with Care
From your first screening colonoscopy to advanced diagnostics, we walk you through every step — because understanding what's happening matters as much as the procedure itself.
Colonoscopy
Colonoscopy is the gold standard for colorectal cancer screening. The American Cancer Society recommends screening begin at age 45 for average-risk adults. Our gastroenterologist performs colonoscopies using high-definition equipment for maximum detection accuracy.
Learn More →Upper Endoscopy (EGD)
Esophagogastroduodenoscopy (EGD) allows your gastroenterologist to examine the lining of your esophagus, stomach, and upper small intestine. This 15-to-20-minute procedure helps diagnose GERD, Barrett's esophagus, ulcers, celiac disease, and more.
Learn More →Capsule Endoscopy
Capsule endoscopy uses a tiny, swallowable camera to capture thousands of images of your small intestine — an area that traditional endoscopy and colonoscopy cannot fully reach. Ideal for diagnosing obscure GI bleeding, Crohn's disease, and small bowel tumors.
Learn More →Hemorrhoid Banding
Rubber band ligation is a quick, minimally invasive in-office treatment for internal hemorrhoids. The procedure takes less than a minute and provides lasting relief from bleeding and discomfort without surgery or general anesthesia.
Learn More →Esophageal Dilation
Esophageal dilation gently stretches a narrowed section of the esophagus to restore comfortable swallowing. It is commonly performed during an upper endoscopy for patients with esophageal strictures caused by GERD, eosinophilic esophagitis, or radiation therapy.
