Maryland Diagnostic and Therapeutic Endo Center - your #1 choice for colonoscopy in the greater Annapolis area!


Recognizing that some patients would prefer a more soothing, private clinic to the hustle and bustle of a hospital, the partners of Digestive Disorders Associates (DDA) joined together to create Maryland Diagnostic and Therapeutic Endo Center (MDTEC) a state-of-the-art surgery center in Annapolis. 

You can schedule your minimally invasive outpatient procedures at MDTEC to help detect, evaluate, and treat a full range of digestive diseases and disorders afflicting the esophagus, stomach, intestines, liver, pancreas, and gallbladder. In addition, MDTEC is proud to offer patients the option of open access colonoscopy, which allows you or your doctor to schedule a routine colonoscopy directly with MDTEC, often bypassing the need for a referral or consultation. 

MDTEC invests in the most technologically advanced equipment, and our physicians are trained to use the most up-to-date procedures and test to help diagnose and treat your issues. We understand that discussing your digestive problems may be uncomfortable for you, but please know that gastrointestinal disorders are typically treated successfully when diagnosed early.

This website gives you easy access to our surgery center and also our gastroenterology practice, (DDA) including:
