Who we are
Prior to founding MM&Co. at Compass, Maggie Marshall began her professional life in public relations, event planning, and marketing for leading firms, including BWR and Starwood Hotels & Resorts for New York's W Hotel locations. In this chapter, she attained valuable experience working with celebrities and high-profile clients who require excellent service, delivered with utmost discretion.
With an innate instinct of where to go next, she pivoted to real estate after buying her first apartment in 2004 before the industry became rebranded through the glamorous lens of hit TV shows. She was hired by AJ Clarke Real Estate where she handled the rental portfolio for the company before joining The Corcoran Group as a solo agent. Her experience with A-list clients gave her a particular niche piquing the interest of top luxury agent, Raphael DeNiro who offered an opportunity she could not pass up. She went to Douglas Elliman in 2008 where she served as the Director of Operations for The De Niro Team. After a 16+ year run, and over $1 billion in sales under her belt, including time spent as a solo agent where she ranked #35 in New York in RealTrends Verified, she joined Compass to form MM&Co. | The Maggie Marshall Team.
Maggie’s gift at creating genuine connections has lent her sterling reputation in the industry. After twenty years, her market knowledge of Manhattan and Brooklyn is bar none. With an authentic goal to see her clients happy, and a problem-solving mindset that can smooth any bump in the road, Maggie provides a steady pair of hands throughout the buying or selling process.
