MATHIEU'S BIOGRAPHY

Mathieu Goldenberg is a real estate agent with Highline Residential in Manhattan, where he combines a strong academic background with a hands-on understanding of the brokerage business. A graduate of the historic St. Paul’s School in Concord, NH—where he was a recruited varsity hockey player—Mathieu brings discipline, resilience, and teamwork to every client relationship.

He views brokerage not just as a profession, but as a way to connect the theory of real estate with its practical realities. By working directly with clients on negotiations, deal structuring, and the transaction process, Mathieu is building a strong foundation that also supports his long-term interests in real estate finance, private equity, and investment strategy.

Mathieu’s goal is to provide clients with thoughtful guidance, clear communication, and a big-picture perspective that serves both their immediate housing needs and their future real estate ambitions.
