Raj Devarajan grew up in India with a clear commitment to medicine from an early age. At fifteen, he entered Madras Medical College, beginning medical school while many students were still considering their plans. That early start showed the focus and discipline that would shape his long career. After medical school, Raj moved to the US for advanced training. He completed 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 developed a broad clinical background that enabled him to understand patients through both physical and behavioral factors. In 1994, Raj founded Middlesex Gastroenterology, PC. Over 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, supporting 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 help patients receive care more efficiently outside the hospital. He served as the facility's President until 2023. Raj's leadership roles 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 simple language. He also holds a share of a patent for an HCA drug formulation tested worldwide and currently awaiting FDA approval. Outside of medicine, he 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 applies his clinical background and regulatory experience to support drug development programs and continue contributing to medicine at a broader level.
