"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."
