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 group of entities 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!

Corporate Events / Private Parties

Employee picnics, product unveilings, investor events, concerts, fashion shows, charitable events & everything in between.

From physical locations to mobile pop-up stores, from art installations, to NYSE IPO celebrations.  The possibilities are endless... If it can be done, we will do it! Go crazy, we dare you!

Specialized Transport / Trucking

Does your event require oversized loads or transporting precious cargo?  We have moved items that left no words to say but, "Only in New York!" Specialized set pieces, 7-figure valued Concept Cars, Space Ships, Live Plants/Animals, 30-Foot tall human dolls... we've moved it.
