I lead the team so the owner doesn't have to.

25+ years in high-end residential construction. Trained in how teams perform.

I spent my first ten years as a construction manager before moving into owner representation. That's 25+ years inside high-end residential teams — long enough to see what allows projects to move cleanly, and what quietly slows them down.

I understand the mechanics of construction. What makes the work different is how I build teams that hold themselves accountable — so the project doesn't depend on one person pushing every outcome.

How I Lead Differently

Construction judgment. Trained in how teams actually perform.

Most owner's reps bring construction knowledge. I bring construction knowledge plus formal training in negotiation through the Black Swan Group and certification in Executive and Team Coaching through Erickson Coaching International.

That combination lets me recognize the patterns most project leaders can't see — where decisions are stalling, where accountability is breaking down, where the team is starting to protect itself instead of the project. And it gives me the tools to interrupt those patterns before they become expensive.

The construction experience tells me what should be happening on the project. The training tells me why it isn't — and how to fix it.

How I Lead Projects

Close to the team. Ahead of key decisions.

The work is steady, not heroic. Most of it happens before problems become problems — in the conversations where decisions get framed and the moments where alignment quietly slips.

Decisions arrive with options.

Tradeoffs are visible.

Accountability is shared, not imposed.

The result is a project where the team holds itself to a higher standard than any owner could enforce — and stays aligned as complexity increases.

The Firm

Second-generation. Built on relationships, not volume.

Dubrow Group is a second-generation family business founded by Marc Dubrow with over four decades of experience in projects of all scales within the Hamptons.

We're a boutique firm by choice — small enough to give every project our full attention, selective enough to take on the projects we can actually lead well.

We began as a construction management practice and grew slowly, building the local relationships with architects and contractors that still anchor the firm today.

In 2010, Justin transitioned the firm from construction management to owner representation. The practice has since evolved further with the addition of Project Leadership — a model for owners who want to stay involved without carrying the project themselves.
