NYC born and raised, William is a 4th generation New Yorker who began his real estate career in 2007, focusing on residential sales and incorporating commercial leasing when the condo market started to boom. He is a Licensed Real Estate Broker, and an accomplished professional who served as Vice President of the Manhattan MLS, as well as an officer of the Manhattan Association of Realtors.
Praised as one of the most enthusiastic and well-educated brokers in the city, William just as much impresses clients with his honesty and integrity. He is down to earth, relatable to anyone, and puts people at ease within the first few minutes of meeting. His sales have spanned Manhattan (where he owns property), Brooklyn, Queens, the Bronx and Westchester markets and included property types of all kinds: from co-ops and condos to townhouses, single and multifamily homes, landmarked buildings, to penthouses and commercial spaces.
An excellent negotiator, William always has his clients’ best interest at heart. He is willing to walk away from a deal that doesn’t work for them, and knows when to push with unique and creative ideas when they truly want a specific property.
“I’ve guided new homebuyers who were once renters and those brand new to the city. I’ve worked with investors looking to secure properties that generate the highest possible revenue, and that are safe havens to invest their capital. I’ve also navigated customers through the often stressful rental process and work with them amicably, as I care more about garnering their respect for a future relationship than anything.”
He also obtained Certifications for Residential Property Management and for Violation Removal from HPD. He received the Ambassadors Award for being the second highest-grossing agent in his prior office, and has been featured in numerous publications like The Real Deal, Brokers Weekly and The New York Post.
William enjoys travel, nature, camping and hiking in his free time. He is also an avid beach goer in summer and snowboarder in winter. Dancing and impressionist art are among his other hobbies.
