Garry O’Neill
Boston Real Estate Agent

Garry is a versatile real estate professional with hands-on experience in buying, selling, leasing, renovating, and managing properties across the Greater Boston area. His real estate journey began in the 1990s as a hobby renovating single-family homes in the suburbs, which quickly evolved into a true passion. Since becoming a licensed real estate agent in 2017, Garry has helped numerous clients navigate the market with confidence—whether they’re searching for their dream home, investing in property, or listing a space for rent.

In addition to his work in real estate, Garry holds a BA in Music from The Boston Conservatory, where he studied trombone in both classical and jazz performance. He has toured internationally and performed with well-known artists, bringing the same discipline and creativity to his real estate career. When he’s not closing deals or overseeing renovations, Garry enjoys golfing and spending time with his partner and their blended family of five children.
