Justin Dubrow

A lifelong Southampton resident who brings a unique skill set to every project, Justin has been involved in construction management and owner representation throughout his professional career, helping build the family-owned Dubrow Group into a successful enterprise on the East End.

Justin’s professional career as a part of the family-owned business started almost 20 years ago when the focus was on construction management and coordinating the day to day operations in the field during the construction phase of the project.  Working directly with subcontractors performing the work Justin managed bidding, scheduling, budgets and daily activity onsite ensuring plans and specifications were followed as intended.  This onsite experience fostered the necessary knowledge of all aspects of construction and how the different parts of a house come together to form the completed project.

After 10 years of working as a construction manager Justin took the lead of Dubrow Group and transitioned the company into an Owner’s Representation role.  No longer managing the day to day site activities, Justin assembles the project team and monitors all phases from conception through completion acting as a direct agent to the client and advocating on their behalf.  

"I have a passion for architecture and construction, I understand that purchasing and building a home is a huge expense for a family and I really enjoy working on that project with them.”

Marc Dubrow

Founder of the Dubrow Group, Marc has been involved with construction in the Hamptons for over 4 decades. Over the years Marc has built long-term relationships with clients and industry professionals alike, who have trusted him with overseeing a breadth of projects of all archetype throughout the East End.

After attending Southampton College, Marc decided to make Southampton his home. Starting as a subcontractor, eventually evolving to full construction management, and currently owner representation with Justin at the helm, bringing a second generation and continuity to the business.


"It gives me the greatest pleasure to write this letter of recommendation of Justin Dubrow. As a principal of a second generation family owned construction business, Dubrow Group, Justin was responsible for the two (2) recent renovation projects we undertook in our Summer home in Remsenburg. Both projects were reasonably straight forward, but for the fact that it was in a 100+ year old home. Throughout the entire project, Justin was available to offer innumerable suggestions as to design alternatives and material, both of which had a direct impact on cost and time. His presence on the job was always noticeable and he was able to offer informed guidance throuhout. He has always exhibited a transparency and forthrightness not generally found in the construction industry. I look forward to working with him again on our next project."

 "Justin has worked for me on-and-off for over a year now as an owner's rep. Originally I selected him because of his GC work on a modular project in East Hampton, which gave him the in-depth knowledge of modular construction I was looking for. I soon realized he is a great resource when it comes to any type of construction. He has strong contacts throughout the Hamptons construction industry, from GCs, to subs, to legal advice. He has expertise in bid analysis, contract structure, and on-site project management. I look forward to working with him again in the near future."

"Marc literally stepped in and saved our construction project from disaster 10 years ago and we have been satisfied clients of him ever since. Dubrow Group took over the building of our home and completed it when another contractor failed to do so. They made a number of repairs to the existing project as well as initiating and managing new construction projects with us. From the first day on the job,  they  have always been professional, trustworthy, honest and have provided top notch service in all areas.  Their many years of experience in dealing with all types of contractors and sub contractors as well as service providers of all kinds has benefitted us many times over. Whether in negotiating contracts for us or just providing a supervisory role, their support has been invaluable.  We recommend them whole heartedly for construction, project management, owner's representation, caretaking or any combination of the above."

-Jody Martini, Sagaponack, NY


"Managing a construction from NYC was nearly impossible. The Dubrow Group made the project a pleasure by representing my interests every step of the way. They are knowledgable, responsive and communicative. I have and will continue to recommend The Dubrow Group to all of my friends."
