Raj Devarajan Male • United States of America

Raj Devarajan grew up in India with a clear interest in medicine and a strong sense of direction. At fifteen, he entered Madras Medical College, beginning medical school while many students were still deciding what to study. That early start showed the focus that continued throughout his career.


After completing medical school, Raj 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 gained a broad clinical background that helped him understand patients through both physical and behavioral health 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 care for problems 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 serve patients more efficiently outside the hospital setting. He served as the facility's President until 2023.


Raj's leadership included service as President of the Medical Staff at Emerson Hospital from 2015-2017 and as a Board member from 2015-2019. 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 took part in television interviews to explain common gastrointestinal diseases in clear language. He also holds a share of a patent for an HCA drug formulation tested worldwide and currently awaiting FDA approval.


Outside of medicine, 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, leveraging his clinical background and regulatory experience to support drug development programs and advance medicine on a broader scale.
