Sabrina Silva

Real Estate Advisor

sabrina@columbusandover.com

Sabrina Silva is a trilingual, Emmy Award-winning former journalist turned real estate agent and entrepreneur, bringing a fresh, energetic, and people-first approach to Boston’s real estate scene.

Before jumping into real estate, Sabrina spent nearly a decade working for TV stations across the country, including WHDH in Boston. Her background as a journalist honed her storytelling, communication, and negotiation skills—tools she now leverages to advocate for her real estate clients. She uses modern marketing tactics, including social media strategy and video production, to give her clients an edge.

Fluent in English, Portuguese, and Spanish, she is especially adept at connecting with diverse communities. 

A proud Brazilian and resident of Back Bay, Sabrina is deeply engaged in the local community. Her mission in real estate mirrors that same commitment: to uplift, empower, and guide others through one of life’s most important decisions.

When she’s not closing deals, you’ll find her enjoying musical theater, fitness  classes, working on her jewelry business, exploring the city, or traveling internationally.
