From Conception to Completion.
Heletz Group is a vertically integrated real estate firm that operates across every phase of the project lifecycle — from ground-up development and affordable housing to luxury condominiums, custom-built single-family homes, strategic acquisitions, and complex assemblages.
Development, construction, and property management are executed through Excel Development Group — the firm's operating arm, founded in 2014.
Driven by Vision, shaped by Innovation, delivered with Precision.
Vision
We recognize potential early — physically, financially, strategically — and we've built our entire approach around the ability to pursue it with purpose. Design, creativity, and foresight shape the way we bring that potential into focus. That clarity is what turns an idea into something real.
Innovation
We don't wait for the obvious path. When conditions shift and complexity stacks up, we find the angle. Resourcefulness isn't a fallback for us — it's how we operate from day one.
Precision
Big vision means nothing without the discipline to execute. Every stage — planning, budgeting, construction, delivery — is managed with the same level of control and attention we brought to the original idea. That consistency is what makes the work last.
Mikhael Heletz
Mikhael Heletz is the Founder and Chief Executive Officer of Heletz Group. At a young age he entered real estate with a clarity of purpose that would define everything that followed.
He began in capital markets financing real estate before moving to acquisition and development in 2009 — building and repositioning multifamily buildings across New York City when the neighborhoods he operated in were overlooked and undervalued. Crown Heights before the market arrived. Bedford-Stuyvesant before the buyers came. Long Island City when it was still masonry yards and steel shops. Distressed assets others walked away from. Luxury markets pioneered before the broader market arrived. Complex assemblages, rezonings, and air rights strategies that required a depth of knowledge most developers don’t have and a willingness to do the work most won’t.
The work reached beyond New York — co-developing Monad Terrace in South Beach, a 59-unit luxury waterfront condominium on Biscayne Bay designed by Pritzker Prize-winning architect Jean Nouvel, in partnership with JDS Development Group.
Over two decades that became Heletz Group — a vertically integrated firm with over $500 million in project value across New York and Miami. Every phase understood. Every phase controlled from within.
