Mary Black Flaherty About Mary Black

Agent

Originally from the suburbs of Philadelphia, Mary has proudly called Westchester home for more than 15 years. Before launching her real estate career, she spent about a decade as an elementary school teacher and educational evaluator.  She taught locally in Westchester ( in the White Plains and Rye City School Districts). That background gave her a deep understanding of local schools, neighborhoods, and the importance of finding not just the right house, but the right community.

As both an advisor and a parent, Mary knows that buying and selling a home is one of life's biggest decisions. She combines her passion for real estate with extensive knowledge of the Westchester market to help buyers and sellers confidently navigate every stage of the process. Known for her responsiveness, thoughtful guidance, and strong negotiation skills, Mary is committed to making every transaction as seamless and successful as possible.

Mary's firsthand experience building her own custom home alongside her husband, a Westchester contractor and business owner, provides her clients with valuable insight into construction, renovations, and home systems. Whether advising buyers evaluating a property's potential or helping sellers prepare their homes for market, she offers practical knowledge that extends beyond the traditional real estate experience.

Deeply rooted in the Rye and Sound Shore communities, Mary has dedicated years to volunteering and supporting local organizations. She has served in leadership roles within school associations, chaired fundraising events benefiting her children's schools, and volunteered with with fundraising events in the communinity.  Her commitment to the community reflects the same care and dedication she brings to every client relationship.

Mary lives in Rye with her husband and their four children. Outside of real estate, she enjoys exploring Westchester's vibrant restaurant scene, biking along the waterfront with her family, spending time at the beach, and discovering new places to travel together. 

Whether you're relocating, purchasing your first home, searching for your forever home, or preparing to sell, Mary is dedicated to providing exceptional service, trusted advice, and a personalized experience from start to finish.
