As Calvert County, Maryland’s first local, doctor-owned endoscopy center, Calvert Digestive Disease Associates offers care that is personal, innovative, and financially mindful.

The CDDA Difference



With a combined 35 years of Gastroenterology experience, CDDA is unparalleled in digestive disease care for Southern Maryland.



Because CDDA is locally owned, we eliminate the middleman. Meaning, your initial visit, procedure and follow-up care is provided exclusively by our own doctors and staff.



Our doctors, who are passionate for care they provide, founded CDDA. Because of this, we have little third party overhead costs, allowing us to provide high level care at affordable costs.

Patients’ Words

I was very nervous when I went to see Dr. Bright. She was absolutely wonderful. She took so much time to explain everything to me. She gave me all of the information I needed to make a decision regarding how to proceed and I felt absolutely comfortable with her. I am so blessed that I got Dr. Bright. She was great.

I will choose Dr. Bright next time and I recommend her to my family and friends. The staff were kind, caring and relaxing. Dr. Bright’s manner put me at ease immediately and she was very caring afterward.

Dr. Rhodes is very thorough. She listens and understands patients’ questions and answers them with common sense. She has superior experience and is extremely proficient.

I had a second procedure with [Dr. Rhodes] and she was very professional. Bedside manner was friendly. Most of all, she was informative at both the office visit and before and after the procedure.
