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 2,000+ 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 leverage AI-powered 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.
