Manchester Connecticut headquarters building at dusk

Welcome to Fuss & O’Neill!

Since 1986, these historic and repurposed mill buildings have been home to Fuss & O’Neill’s corporate headquarters, which was originally the site of the Cheney Brothers Silk Manufacturing Company, for whom our founder originally worked.

The largest of our offices, these two buildings support employees that provide our full suite of multidisciplinary services, our corporate services departments, and our executive team. Our corporate headquarters, with its full staff of wide-ranging technical experts working together on solutions to our government agency, industrial, utility, developer, architectural, private, and municipal clients’ needs, sets the foundation for the principle of collaboration that permeates throughout our network of offices.

It is our collaboration, across fields, services, and experts, that truly sets us apart. Teamwork is fostered and encouraged, both internally and externally, as it best serves our clients’ goals by bringing them complete solutions and empowers our staff to flourish.

Our corporate headquarters supports our goal of using renewable energy through rooftop solar and renewable energy certificates (RECs) for all purchased electricity and partakes in food waste composting.

Fuss & O’Neill’s company headquarters offers clients the entire breadth of the firm’s multidisciplinary services. Our Connecticut-based experts collaborate with our regional network to implement creative solutions throughout New England.
