Sherry Costello Real Estate - Meet Sherry Costello

Sherry’s path to real estate was a journey rather than a destination, a journey she always wanted to travel and one that continues to grow and evolve today. She is a firm believer that every home has a story, and she considers herself fortunate to have been a part of so many stories over her 13 years in real estate.

Sherry’s roots run deep in the area. She attended school in Waltham and spent her summers in the Rexhame Beach area of Marshfield. Upon completing her education, she began her professional career focusing on sales. She worked as an Administrative Recruiter, where she quickly became a top producer before moving into a role as a Sales Coordinator for a major publishing company.

Sherry made her home permanently in Marshfield 30 years ago to raise her family. As a single mom,Sherry held down a full-time job while raising her children. After feeling the pull of her calling, Sherry began working toward her real estate license in 2009. In 2014, she took the leap and launched a full-time real estate career.
