About Tonya L. Adams, MD

Dr. Adams knew at an early age that she wanted to pursue a career in healthcare. In high school she volunteered at a local hospital, and was later accepted into the School of Nursing at the University of Michigan. After three years of Nursing School she decided to shift her interest to Medicine and changed her major to Biology/Pre-Med. She excelled in Medical School, where she was awarded the Pathology Student Fellow Award and spent a year doing clinical research and student teaching.

During her Internal Medicine Residency at The Johns Hopkins University Medical Center, Dr. Adams found the intellectual and technical aspects of Gastroenterology appealing and decided to seek sub-specialty training in the field. She later completed Gastroenterology Fellowship training at Georgetown Medical Center during which time she served as the only trainee member on the American Society of Gastrointestinal Endoscopy (ASGE) Committee on Membership Training.

Dr. Adams joined Gastro Health in 2002 and was named one of the area’s “Top Doctors” for Gastroenterology after only five years in clinical practice. She was a previous member of the Washington, D.C. Advisory Board of the Crohn’s and Colitis Foundation of America, and served as Chairperson of the ASGE’s Diversity Committee. She has presented to members of Congress on the importance of funding support for colorectal cancer screening, moderated sessions at national Gastroenterology meetings and continues to be quite active in community education programs.

Dedicated to helping women understand gender-specific digestive health issues and assisting all patients in preventing colon cancer, Dr. Adams presented “What everyone should know about Colon Cancer Screening” at the 2019 Women’s Health & Wellness Summit. Dr. Adams gave a thorough overview of screening guidelines and encourages anyone 45 years of age, or earlier if symptomatic, to get screened for colon cancer.
