About Me

I am a gastroenterologist specializing in the evaluation, management, and prevention of diseases involving the digestive tract. I strive to provide timely, effective, efficient, safe, equitable and patient-centered care during every patient encounter. Additionally, I utilize my training and expertise in medicine, public health and health policy to educate and advocate for my patients. One area in which I am extremely passionate about doing so is in colorectal cancer prevention and screening.

I completed medical school at Howard University College of Medicine, residency in Internal Medicine at Duke University Medical Center, Gastroenterology fellowship at Washington University in St. Louis, and a Master’s of Public Health at Harvard T. H. Chan School of Public Health. Currently, I serve as an assistant professor of medicine, director of Community Engagement and Equity in Digestive Health, medical director of Endoscopy and Gastroenterology Services at University Hospital East and deputy director at the Center for Cancer Health Equity at the OSUCCC – James.

At OSU Wexner Medical Center and the James Cancer Hospital, I enjoy the team-based approach to care. I work with doctors, nurses, researchers, and administrators to provide the best possible care to our diverse patient population. It’s a community that incorporates teaching, innovation in research and clinical care.

    Dr. Darren M. Gray was very professional, knowledgeable in his skills and explain & answered all my concerns about my condition. He is the best listener. Took the time to call me himself about my test results. Made me feel special as a patient of his. Like family to me, lol. I knew in my heart he will take good care of me.

    Dr. Gray is wonderful! He worked to get me in at the end of the day to help work around my schedule. He listened & engaged me in creating my plan of care.

    Dr. Gray was highly recommended. He was willing to overbook me in an effort to address my immediate need. He appears committed to finding a resolution to my stomach issues. I've been to multiple gastro. over the years and I've found "the one" who is open to thinking outside of the box.
