Mark B. Taylor, M.D.
Chairman of the Board
As chairman of the board, Mark spearheads recruitment and strategic planning for growth of the organization. PACT was born from Mark’s vision five years ago and brought to life with PACT’s leadership to create an organization in which physicians across specialties could unite in order to preserve private practice in our community. PACT and PACT MSO opened its doors in the fall of 2013. He is working on potential ancillary services.
Mark graduated from the University of Rochester and simultaneously obtained a master’s degree in gerontology from the University of Chicago. He attended medical school at Tufts University, did his residency in internal medicine at the University of Chicago’s Michael Reese Hospital and completed his gastroenterology training at Harvard Medical School’s Beth Israel Hospital. He’s been a practicing gastroenterologist in this community for more than 25 years.
After spending eight years as a gastroenterologist in this community, Mark asked two other gastroenterologists to join him in a new venture, and together in 1997 they started Gastroenterology Center of Connecticut (GCC) in Hamden. This was soon followed by the Endoscopy Centers of Connecticut in Hamden; and then in Guilford, the Medical Research Center of Connecticut, Pathology, Celiac and Liver centers. GCC now has offices in Hamden, Milford and Guilford.
Mark is the editor-in-chief of two major gastroenterology textbooks: Gastrointestinal Emergencies Volume I, published in 1992, and Volume II, which was published in 1997 and translated into Chinese. These textbooks are still used by many of the leading fellowship programs in United States. Dr. Taylor has been chosen as a “Top Doc” by Connecticut Magazine for the past nine consecutive years until 2017 when Top Docs was absorbed by “Connecticut Best Doctors” where he has been honored for the past 25 consecutive years. He also is featured in Cambridge edition of Who’s Who. He is former chief of gastroenterology at Milford Hospital, a former managing partner of GCC, and he now serves on the executive governing board of the practice. Mark is proud of the work done by the PACT leadership and its board of directors who give generously of their time and talents to keep PACT growing and staying current with the ever-changing medical landscape.
What our employees are saying
As a physician assistant/advanced practitioner I have found PACT to be welcoming and eager to listen. The culture in my office is warm and friendly. The best part of my job is coming to work knowing that I’m appreciated and making a difference.
