John has completed over 250 transactions in his twelve plus years in Real Estate Brokerage, with a keen eye for the Manhattan and Brooklyn townhouse market while also working on condominiums, co-ops and rentals. John's first year in Brokerage saw him begin with a $3,000 rental client to showing multi-million dollar homes on a daily basis. He spent his first six months in New York City Real Estate without making one dollar and now with twelve years of experience, John is excited to continue his work at SERHANT.


John has worked with several top teams in the city, consistently ranking on Wall Street Journal's Real Trends Top Brokers. A global network, strong relationships in the brokerage community and hand in hand work with developers, landlords, sellers and buyers throughout New York City, John's clients receive extraordinary service and profound advantages in the market.


Being born and raised in New York City from two third generation Brooklyn families, Real Estate and Baseball have always been John’s passion. Real Estate came from his Grandfather who owned and managed a multifamily portfolio in Brooklyn. Baseball from his other Grandfather 'Lefty' Keenan who played professionally with the Brooklyn Dodgers. John inherited his left arm and pitched for Xaverian High School’s City Championship team of 2008, ranked #20 in the nation. He went on to pitch for Manhattanville College where he graduated in 2012.


Within his twelve+ years in Real Estate, John has acquired invaluable knowledge in real estate brokerage as well as property management and development. John works to manage and develop investment properties throughout Brooklyn and Florida. John understands how demanding the search for the perfect property can be, and takes the utmost pride in seeing his clients through the finish line.
