About Milton

A Lifelong New Yorker

Born and raised in Inwood and Washington Heights, my journey into real estate began while working at a nonprofit surrounded by NYC's top developers. Intrigued by the business, I launched my career in Fall 2001 and never looked back. At my former company, I rose to Managing Partner and Principal Broker by excelling in technology, marketing, and exceptional service.

With 1,000+ transactions across residential, commercial, and investment properties in all five boroughs, I joined Keller Williams NYC in 2016 to continue delivering results. A lifelong learner, I use data-driven tools, automation, and cutting-edge technology, from custom property websites to predictive market analysis, to give clients a competitive edge.

Beyond real estate, I'm a proud 2x girl dad, my greatest motivation. When not closing deals, you'll find me cheering for the home team or exploring the world. Hablo Español. I represent NYC buyers and sellers as a bilingual real estate agent, in English and Spanish.

Client Voices

Broker Performance

Buyer • Manhattan

"Milton helped me purchase my first Manhattan condo, and I can't recommend him highly enough. What could have been a stressful process ended up feeling remarkably smooth. From the initial offer through closing, Milton was responsive, knowledgeable, and always willing to take the time to answer questions and explain the details. I always felt informed and supported, but never pressured. If you're looking for a broker who is knowledgeable, trustworthy, responsive, and genuinely invested in helping his clients succeed, I would absolutely recommend Milton."
