New York
Nearly a century ago, Adolf G. Syska and John F. Hennessy laid the foundation for what would become Syska Hennessy Group—a firm dedicated to shaping the future of cities. Our story began here in New York in 1928, and today, our headquarters sits in the heart of Manhattan, just steps away from Times Square and 42nd Street.
Our New York services go far beyond the basics. We specialize in not only MEP engineering, but also in commissioning, architectural lighting, fire protection, facility management, sustainability, and information and communications technology (ICT), across a wide range of sectors: mission-critical, healthcare, aviation, commercial, industrial, mixed-use, and science and technology. From our headquarters, we continue to influence the built environment not only across New York City, but also throughout the United States and around the globe.
Clients & Projects
Our New York team partners with some of the most respected organizations in the world, delivering solutions that transform communities and drive meaningful progress. Our client roster includes renowned entities such as Brooklyn Borough Jail, Columbia University, Mount Sinai Medical Center, Bloomberg, NewYork-Presbyterian Hospital, ADP, AIG, JPMorgan Chase, Blackrock, and SL Green.

Culture
Life in New York is fast-paced, energetic, and inspiring—qualities that shape our office culture. While we thrive on the excitement of The Big Apple, we also value giving back to the community and supporting causes that matter.
We proudly champion organizations like Girls Inc., helping to empower the next generation of leaders, and we mentor high school students interested in architecture, construction, and engineering through the ACE Mentor Program of America. Our team combines fun with philanthropy, hosting events such as the Breast Cancer Game Night to raise funds for lifesaving research.
