Liam Treanor


Liam is an analytical, energetic, detail-oriented Chief Operating Officer with more than 25 years of broad experience and deep knowledge in high level commercial and residential construction projects. He started his career working as a carpenter’s helper for his brother-in-law, grew to finish carpentry working in high end McMansions and homes on the north shore in Long Island. Liam moved on to work as a framing carpenter learning extensions and dormers, timber framing, roofing, siding, framing of houses and foundations. At 25, he was offered the opportunity and took over his brother-in-law’s business doing finish carpentry while bartending in Manhattan, making business connections, and moving from residential building to hospitality building bars, restaurants, nightclubs and lounges, growing from a subcontractor to a GC. A perfectionist, he strives for quality work and clients loved that he was always reliable and could work 24/7. Eventually growing big enough to not only be a GC at most hospitality venues in Manhattan, he was also hired as a Sub by other larger GC’s, essentially having played a part in building most clubs and lounges in all of Manhattan. Liam also replicated work from only a picture & took designers’ and clients’ visions with one-of-a-kind designs, making them a reality.
