About Us

Cormac O'Brien's of New York, LLC was founded with one goal in mind: to serve the Construction & Special Events Industries in producing creative and unforgettable projects for every occasion. From small intimate venues to large-scale build-outs and corporate events, we strive to execute in a way that not only aims to impress, but also create unique experiences for our clients and their guests that last long after the fun is over.

We are a family owned & operated company originally formed by Michael O'Brien in 1972.  Joined by his 3 sons Cormac Ronan & Conall, they have continued to offer quality workmanship with a personal touch that is a rarity in the industry.

Please feel free to reach out to us directly with any questions or ideas for your next project!
