John Gasdaska – The Corcoran Group



John Gasdaska embraces each day at a time, with his first thought always of how he can be of service to others. This philosophy has never failed him, and helped him catapult his real estate business. Licensed since 1999 when he made the transition from the luxury hotel service industry, John specializes in selling residential real estate throughout Manhattan. He is a longtime annual member of Corcoran’s prestigious Multi-Million-Dollar Club, and consistently ranks in the Top 1% of 64,000 NRT Agents nationwide.

In his tenure, John also served as Director of North America for Corcoran’s International Division, working directly with founder Barbara Corcoran and a team of top agents. In 2006, he formed a significant partnership with seasoned Corcoran broker, Jonathan Conlon. Their mission is to deliver the most superior, comprehensive, 24/7 expert service to their diverse, discerning clientele that includes high-profile New Yorkers in all fields of endeavor.

John’s personalized service, market knowledge, savvy negotiating skills, and thorough guidance streamline the purchase or sale process, and truly set him apart. Yet his true key to success are the relationships with his clients. “Once a client, always a client,” he believes. These lasting bonds far outweigh simply making a sale; and the praise John receives are a testament to that:

“John Gasdaska is exceptional. You can’t fake passion, and John’s true love for his clients makes for tremendous success.

If you want honesty, great salesmanship, and extraordinary results, John’s the man. You can’t find a more dedicated professional than him.” 
~ Barbara Corcoran, Founder, The Corcoran Group.

“John went out of his way to work with me and my schedule. He handled a difficult opposing broker with ease and grace and always communicated when things changed unexpectedly with clarity and concern. My experience in dealing with him was truly exceptional.” 
~ Erika Klauer, Analyst, Jennison and Associates.

A Pennsylvania native, John holds a Finance degree from Villanova University. Before real estate he was Chief Concierge and Front Office Manager at Ian Schrager’s Royalton Hotel. Living in Manhattan for 30 years, with homes in the city and Hudson Valley, John is married and has a poodle named Bear. He is a very active volunteer at his Catholic Church, and in his community. He enjoys gardening, golf, theater, opera and travel and currently sits on on the Board of the off-Broadway Abingdon Theatre Company.
