Zach Grossman

Zach Grossman brings a builder’s eye for quality and a modern perspective to Hamptons real estate.

Before becoming an agent, Zach spent a decade working alongside his father, Jon, building luxury homes across the East End. From foundations and framing to finishes and floor plans, he learned the business from the ground up—developing a deep understanding of construction quality, design, and long-term value that few agents can offer.

That experience gives Zach a distinct advantage when evaluating a property. He can quickly assess what’s behind the walls, identify opportunities for improvement, and help clients understand the real cost—and potential—of a home. Whether advising sellers on strategic enhancements to maximize return or guiding buyers through a property’s condition, renovation possibilities, and future value, Zach approaches every transaction with the trained eye of a builder and the perspective of a trusted advisor.

Born and raised in East Hampton, Zach’s connection to the area is both personal and professional. He knows the neighborhoods, beaches, back roads, and the subtle distinctions that define each corner of the Hamptons—insight that helps clients evaluate not just a property, but the lifestyle and long-term fit that come with it.

Now at Compass, Zach works alongside Jon as part of a true father-and-son team. Together, they bring a rare combination of generational perspective, deep local roots, and hands-on construction expertise. For clients, that means sharper guidance, greater clarity, and more confident decisions—whether buying, selling, or investing on the East End.
