Raj Devarajan

Raj Devarajan grew up in India with a clear interest in medicine and a steady sense of purpose. At 15, he entered Madras Medical College, beginning his medical education much earlier than most students. That early start reflected the focus that would guide his long career in patient care, leadership, and medical development. After medical school, he moved to the US for advanced training. He trained at 3 leading institutions, completing residencies in adult psychiatry at Yale University, child psychiatry at Harvard University, and internal medicine and gastroenterology at Tufts University. When his fellowship ended in 1994, he had built a broad clinical background that helped him understand patients through physical, behavioral, and psychological health factors. In 1994, Raj founded Middlesex Gastroenterology, PC. During the next 29 years, he helped build one of the busiest gastroenterology practices in Massachusetts. Before retiring from clinical medicine in 2023, he performed more than sixty thousand endoscopic procedures. He also founded the ERCP program at Emerson Hospital and Nashoba Valley Medical Center, helping support treatment for conditions involving the bile ducts and pancreas. Raj Devarajan, MD, worked closely with Emerson Hospital, Newton-Wellesley Hospital, Boston Children's Hospital, and Yale New Haven Medical Center. In 2005, he established ASC Middlesex Endoscopy Center, LLC, to support more efficient patient care outside the hospital setting. He served as the facility's President until 2023. Raj's leadership included serving as President of the Medical Staff at Emerson Hospital from 2015 to 2017 and as a Board member from 2015 to 2019. He also served as Past President of the Massachusetts Gastroenterology Association and the American Association of Gastroenterologists of Indian Origin. Beyond healthcare, he founded several companies in other sectors. Raj served as a speaker for Salix Pharmaceuticals, Ironwood Pharmaceuticals, Forest Pharmaceuticals, and AstraZeneca. He also worked as a consultant for Boston Scientific and Pentax Corporation and served on the Medical Advisory Board of Cristcot Corporation and Allurion Corporation. He appeared in television interviews to explain common gastrointestinal diseases in clear, practical language. He also holds a share of a patent for an HCA drug formulation tested worldwide and currently awaiting FDA approval. Outside his professional life, Raj enjoys golf, tennis, chess, bridge, and skiing. He is a father of two adult children and values giving back, including supporting a school in India and volunteering at the Acton Food Pantry. Today, Raj Devarajan serves as Global Medical Monitor at Cristcot, where he uses his clinical background and regulatory experience to support drug development programs and continue contributing to medicine at a broader scale.
