For more than three decades, Gary DePersia has done far more than sell homes in the Hamptons, he has helped define the market itself. With over $3 billion in real estate transactions on the East End since 1995, Gary has built one of the most respected and successful careers in Hamptons real estate, earning a reputation synonymous with excellence, integrity, and results.

Recognized as one of the leading luxury real estate brokers in the Hamptons, Gary’s expertise spans Southampton, East Hampton, Sagaponack, Bridgehampton, Water Mill, Wainscott, Amagansett, Montauk, Sag Harbor, Shelter Island, and the North Fork. His knowledge of waterfront estates, oceanfront homes, village properties, equestrian compounds, new construction, investment opportunities, and luxury summer rentals has made him a trusted advisor to buyers, sellers, renters, developers, and investors throughout the East End of Long Island.

In a marketplace where discretion, relationships, timing, and trust matter as much as price, experience alone is not enough. Results are what matter. And for more than 30 years, Gary has consistently delivered them at the highest level.

Today, Gary remains one of the Hamptons’ top producing brokers and a perennial member of the President’s Council at The Corcoran Group, one of the nation’s most recognized and influential real estate firms. His accomplishments have earned national recognition for nearly two decades, beginning in 2008 when The Wall Street Journal ranked him the fourth highest producing broker in the United States. Most recently, he was recognized as Corcoran’s leading producer on the East End of Long Island in 2024.

When clients hire Gary, they are not hiring someone trying to learn the Hamptons market in real time. They are hiring a broker whose name, face, and reputation are deeply established among buyers, sellers, brokers, developers, attorneys, architects, investors, and the many professionals who influence luxury real estate transactions throughout the Hamptons.

That matters because luxury properties are not sold simply through advertising. They are sold through relationships, credibility, access, negotiation, and the confidence buyers have in the person representing the property.

Over the course of his career, Gary has represented some of the most significant homes from Southampton to Montauk and from Sagaponack to Shelter Island. With hundreds of exclusive listings sold and closed, as well as hundreds of buyers and renters successfully matched to the right properties, he has consistently generated benchmark sales while cultivating an unsurpassed reputation for professionalism and client advocacy.

His portfolio includes oceanfront homes in Southampton and Bridgehampton, waterfront estates on Mecox Bay and Sag Harbor Cove, village residences in East Hampton and Sag Harbor, estate compounds in Sagaponack and Water Mill, equestrian properties, tennis estates, modern architectural residences, historic homes, and some of the most coveted luxury rental properties in the Hamptons.

Markets change. Experience doesn’t.

Gary’s deep knowledge of every village, hamlet, waterfront enclave, beach community, and estate section allows him to advise clients with uncommon insight. Appreciating that each buyer, seller, renter, and investor has a unique vision of what defines their Hamptons experience, he is equally comfortable representing a charming summer cottage, a village home, a waterfront retreat, a development opportunity, or one of the region’s most spectacular luxury estates.

A significant part of Gary’s success stems from the infrastructure supporting his business. He leads an experienced in house team of three licensed professionals who help execute every aspect of the client experience at the highest level. One team member has been with him for nearly 20 years, another for more than 15 years, and a third joined the team three years ago, bringing fresh perspective to an already seasoned operation. This continuity is rare in the real estate industry and reflects the loyalty, professionalism, and consistency with which Gary and his team operate.

Beyond his in house staff, Gary works closely with dedicated marketing professionals and social media specialists to ensure every property receives sophisticated, high level exposure across both traditional and digital platforms. Today’s luxury buyer may emerge through a broker relationship, a private introduction, a targeted digital campaign, social media visibility, editorial exposure, or a referral from another market. Gary’s clients benefit from all of it.

A firm believer in rewarding the confidence of those who entrust him with their properties, Gary has long been recognized as one of the East End’s most prolific and innovative marketers. His exclusive listings are regularly featured across local, national, and international media platforms. Long before digital marketing became commonplace, Gary understood the importance of creating maximum exposure for his clients’ properties. He was among the first Hamptons brokers to launch a personal website and leverage social media as a meaningful marketing tool, setting standards that many others would later follow.

His affable nature, tireless energy, and deep expertise have made him a trusted resource not only for his clients but also for brokers throughout New York City, Palm Beach, Miami, Los Angeles, Aspen, Greenwich, Boston, and across the country who confidently refer their clients to him. Local brokers value his market knowledge and often look to him as a leader in the evolution of luxury real estate marketing and representation.

An inimitable ambassador for Hamptons luxury real estate, Gary regularly introduces audiences to the region’s finest properties through appearances on NBC’s Open House, CBS’s Living Large, and PBS’s Best Places to Live. He is frequently sought out by major media outlets for his market expertise and has been quoted in The New York Times, The Wall Street Journal, The New York Post, The Real Deal, Mansion Global, and numerous other publications covering luxury real estate, Hamptons real estate, East Hampton real estate, Southampton real estate, and the luxury home market.

Whether representing a waterfront estate in Sag Harbor, an oceanfront residence in Southampton, a luxury rental in East Hampton, a modern home in Water Mill, a village property in Bridgehampton, or a legacy estate in Sagaponack, Gary brings the same commitment, professionalism, creativity, and determination to every assignment.

Perhaps most importantly, when clients hire Gary, they are not handed off after the listing agreement is signed. They get Gary himself, his experience, relationships, strategy, negotiation skills, judgment, and direct involvement throughout the entire process. Gary and his team are deeply hands on because representation at this level requires attention, responsiveness, and precision from beginning to end.

There are many real estate agents. Very few become synonymous with the market they serve. Gary DePersia has spent more than 30 years earning that distinction in the Hamptons, one relationship, one transaction, and one successful result at a time.

For buyers, sellers, renters, developers, and investors seeking expert representation in Hamptons real estate, luxury homes, waterfront properties, oceanfront estates, vacation homes, summer rentals, new construction, and investment opportunities throughout Southampton, East Hampton, Sagaponack, Bridgehampton, Water Mill, Wainscott, Amagansett, Montauk, Sag Harbor, Shelter Island, and the North Fork, Gary DePersia remains one of the most recognized, respected, and accomplished names in the business.
