Expert Team

Experience makes the difference and we have some of the area’s most experienced gastroenterologists and colorectal surgeons on our staff. Our specialists have received extensive training for performing colonoscopy and they are supported by experienced technicians and nurses. Specialty training nurses deliver moderate intravenous sedation to patients, to induce a state of twilight sleep for the procedure.


Our endoscopy suite, where colonoscopies are performed, is designed to enhance your comfort during your visit. We use advanced technology that has been shown to procedure the best results.

Continuity of care

If your endoscopy shows signs of cancer, you are in the best place for care. Our surgeons are nationally known for their expertise. You also have access to a full array of treatments at MedStar Health.

Specialized Interventional Endoscopic Procedures

  • Endoscopic ultrasound
  • Diagnostic and therapeutic ERCP
  • Management of gastrointestinal strictures
  • Large polyp removal
  • Management of Barrett’s esophagus
  • Diagnostic and management of gastroenterologic diseases using upper endoscopy, single balloon enteroscopy, and colonoscopy


The Endoscopy Center also offers a wider variety of sedation options for patients. Although some patients prefer moderate sedation so that they will remain awake, others may feel anxious about the procedure. Because the Endoscopy Center offers monitored anesthesia, our patients are much more comfortable and relaxed. Most fall asleep or remember very little of the procedure.
