With over a decade of experience as a realtor serving Southborough, MA, and the greater MetroWest area, Maria expertly guides her clients through the dynamic real estate market. Maria is a breath of fresh air; she is forthcoming and market savvy, utilizing both new technology and proven fundamentals to create a unique marketing plan for each seller.

In 2025, Maria’s strategic approach led to a historic year of production, where she represented three of the top four highest sales in Southborough. This included the record-breaking new construction sales at 6 and 8 Lorenzo Drive in partnership with Bartolini Builders, and the $1.95M luxury resale of 9 Leeds Way, where she served as the expert representative for both the seller and the buyer.

When working with buyers, Maria provides invaluable local knowledge and strategic advice to help them secure the perfect property in competitive markets. Her versatility is evidenced by her success across all architectural styles, including the sale of 157 Parkerville Road, which set the 2025 record for the highest-priced antique home sale in Southborough. Her deep roots in the MetroWest area, combined with a robust marketing and sales background, give her clients a distinct advantage. This expertise extends to unique luxury markets like Sturbridge, where Maria recently set the all-time record for the highest residential sale in the town's history at 220 Hemlock Path on Big Alum Pond ($2,218,500).

Maria's reputation is built on her high-quality standards, exceptional service, and commitment to exceeding client expectations. Consistently a top-producing realtor since 2016, she was proudly included in the prestigious RealTrends Verified rankings in 2024 and 2025, a recognition that places her among the top 1.5% of 1.6 million real estate professionals nationwide.

When she's not helping clients, Maria enjoys raising her twin daughters with her husband and their enthusiastic Wheaten Terrier. She is also a passionate art lover, a dedicated foodie, and a design enthusiast.
