The Slope to Shore Team of William Raveis Real Estate was founded in 2016 by team leaders Heidi Pafumi and Shawna Serricchio. The Team’s volume in sales grew exponentially faster than expected and prompted the addition of its first member, Yahaira Antonmarchi. We have since grown to a team of over 20 agents in Massachusetts, Connecticut, and Vermont.

We have over $200 million in home sales and helped hundreds of clients achieve their real estate goals since our inception. We rank Number 2 companywide in the state of Massachusetts for units sold and in top 10 companywide for volume.

We are well versed in every aspect of the real estate industry and can expertly navigate our way through any transaction- whether it’s finding a dream home for a first-time home buyer or assessing the risk of a project for a seasoned investor. 

People hire us with the expectation of receiving superior service from highly experienced professionals who will work diligently on their behalf- and we deliver every single time. We are top notch negotiators and savvy problem solvers with a vast network of resources at our disposal.

Our agents come from all walks of life, with professional experience ranging in everything from investing & property management, to finance, to marketing & public relations and so much more. So many different backgrounds, different personalities, different areas of expertise, all with the same goal- to serve the communities we love by providing the highest level of service to our clients. 

Multimillion dollar producing Realtors. Investors. Entrepreneurs.
