Manatus Development Partners

About Manatus Development Partners

Manatus Development Partners, led by Justin Stern, is committed to transforming communities through strategic, mission-driven development. We specialize in projects that create long-term social and economic value across New York City’s five boroughs, with a focus on critical community infrastructure such as schools, healthcare centers and administrative offices for not-for-profits.

Through adaptive reuse and ground-up development, we embrace a sustainable, thoughtful, and impact-driven approach that fosters inclusion, resilience, and long-term neighborhood growth. At Manatus, we believe real estate is more than just physical structures—it is a catalyst for social change and economic empowerment.

We are actively seeking collaborations with like-minded organizations, institutional investors, and public-private partners who share our vision for equitable, community-focused development. Whether you are a nonprofit seeking expansion, a public entity with an urgent infrastructure need, or an investor looking to make a measurable impact, we welcome the opportunity to co-create transformative projects that leave a lasting legacy.

Let’s build stronger communities together—one impactful project at a time.
