A New York City native and lawyer by training, Maggie founded MGS Group Real Estate after working at Coldwell Banker. Widely recognized in the industry as a “top broker” for those seeking to buy or sell high-end properties, Maggie knows that being nimble and truly able to think ‘out of the box’ are critical to achieving her clients’ objectives. With her finger on the pulse of the market, Maggie is singularly focused on negotiating deal terms that exceed client expectations. Indeed, Maggie provides more than clear and sound real estate advice — she offers strategic thinking that enables her clients to realize every advantage.

Over her career, Maggie has advised and brokered some of the largest, record breaking and most complicated real estate transactions in her core markets. She is often celebrated as a Top Real Estate Producer in the luxury residential real estate brokerage communities she serves and has been recognized for being a Top Real Estate Broker by the Wall Street Journal. Maggie is also a member of the New York Metro Chapter of YPO.

Maggie resides in Cambridge, MA and the Upper East Side of Manhattan. She has served on several philanthropic Boards and Committees over the past 20 years, including currently serving on the Board of Advisors of Harvard’s American Repertory Theatre and the Board of Philanthropic Overseers of Boston Children’s Hospital.
