Dmitry Finkelberg, MD

The founder of West Suburban GI, Dr. Dmitry Finkelberg brings decades of experience to the practice. He began his medical career at the Novosibirsk Medical Academy in Russia, graduating with an MD in 1989. He then moved to Israel in 1993 for his residency at the Carmel Medical Center/Technion School of Medicine in Haifa and subsequently a fellowship in Gastroenterology there until 2004, when he relocated to Massachusetts.

He completed an internal medicine residency at St. Vincent Hospital in Worcester, and in 2007 started a fellowship in Gastroenterology at UMass Medical Center. After completion of his fellowship in 2010, Dr. Finkelberg joined the Division of Gastroenterology, serving as an assistant professor of medicine at UMass Medical School. He was named a Director of Gastroenterology and Hepatology at Marlborough Hospital in 2012, a position he still maintains. He was an attending gastroenterologist with UMass Medical Group until 2015 and then moved to Milford Regional Medical Center for six years.

In 2021, Dr. Finkelberg established his own practice in Southborough, joined soon after by his colleague from Milford Regional Medical Center, Dr. Daniel Donahue, MD.

Daniel G. Donahue, MD

A lifelong New Englander, Dr. Daniel Donahue did his undergraduate work as an English/Premed major at the College of the Holy Cross in Worcester, Massachusetts. He graduated cum laude in 1983 then headed east on the Massachusetts Turnpike to attend Boston University School of Medicine. He graduated from BUSM in 1988. Then he made the short trek west again for his internal medicine residency and GI fellowship at the University of Massachusetts Medical Center.

His first job out of fellowship in 1993 was on the teaching staff at Baystate Medical Center in Springfield. His academic title was assistant clinical professor of medicine at Tufts University Medical School. While at Baystate he was named Teacher of the Year for the surgical residency program in 1994. He maintained a busy clinical practice while teaching PA students at Springfield College as part of his duties as a Baystate Medical Education and Research Foundation member.

In 1997 he began his long tenure with the University of Massachusetts Medical School as an assistant professor of medicine while on the active staff at Milford Regional Medical Center and an attending physician at Milford Gastroenterology Associates. In 2002, he was named Teacher of the Year for the UMass Medical residency program.

In 2021, Dr. Donahue joined Dr. Finkelberg at West Suburban GI to work part-time in their mutual hometown of Southborough. He remains on the faculty at UMass Medical School and is active staff at Marlborough Hospital.

Outside the medical practice, he is president of the Southborough Village Society, and enjoys light construction and renovation work. The new West Suburban GI office, housed in a nineteenth-century Victorian, has benefited from his varied skills and interests.

His patients regularly give him five-star reviews:
“Thank you for the care and the attention. Dr. Donahue and his team are the best!”
