About John

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.
