Our Leadership
A team of experienced real estate professionals united by a shared commitment to building great communities and delivering exceptional resident experiences.
Experienced Operators, Committed Owners
The Manhattan Development Group leadership team brings together decades of combined experience across multi-family development, property management, and value-add investment. Our principals have overseen the acquisition, renovation, and management of over 1,000 residential units across four states.
What sets our team apart is the owner-operator mindset we bring to every decision. We don’t just manage properties. We own them, and that alignment drives everything we do.
With rental properties spanning four states and all income ranges, MDG’s leadership team is committed to delivering exceptional living experiences at every price point. Our principals combine deep local market knowledge with a disciplined, long-term investment approach.
