Sean McGrath
Stonegate Group
Sean P. McGrath is a lifelong resident of the Boston area and graduated from Bentley University with a degree in Business Management.
Sean founded Stonegate Group in 1988 and, as its Chief Executive Officer, set out to form an elite team specialized in asset management, acquisitions, sales, finance, and development. With over 100 years of collective experience, Sean and his staff have afforded Stonegate the “real vision in real estate” that has guided the company to the success it currently enjoys.
Outside of his real estate endeavors, Sean has branched out into several other related businesses, including lending and joint ventures. With his previous experience as a former owner and franchisee of 25 Dunkin’/Baskin Robbins stores in the Mid-Atlantic region, he is now developing a growing portfolio of Dairy Queen stores throughout Massachusetts. He also owns and operates several solar companies in both Massachusetts and California.
A member of several philanthropic organizations, Sean serves on the Finance Committee of the Roman Catholic Archdiocese of Boston, the Board of Directors of the Eisenhower Medical Center, the Board of Trustees of the Nativity School of Worcester, the Strategic Committee for the Catholic Schools of Boston, and the Board of Directors of The 100 Club of Massachusetts. Past board positions have included the Meadowbrook School of Weston, the Museum of Science, and the Nativity School of New Bedford.
Sean and his wife currently divide their time between the California desert, Boston, and Maine. In his spare time, Sean enjoys golfing, tennis, and spending time on the farm. His three sons all live and work in the Boston area, and all together they make a great golf foursome.
