About Us

Fuss & O’Neill provides the solutions that clients need for their specialized projects. We provide the same focus and expertise to small, straightforward, single-discipline projects as we do to large, complex, multi-discipline ones.

Headquartered in Manchester, CT and founded in 1924, the company has grown to include six regional offices, three LLCs and about 300 employees. Our professional staff maintains licenses and certifications across a wide range of engineering, planning, landscape architecture, design build, scientific and manufacturing disciplines.

Our full service capabilities continue to expand as we embrace sustainable practices. We are corporate members of the United States Green Building Council (USGBC) and have more than 20 certified Leadership in Energy and Environmental Design Accredited Professionals (LEED AP). In addition, we are actively involved in the Congress for the New Urbanism (CNU), the leading organization promoting walkable, mixed-use neighborhood development, sustainable communities and healthier living conditions.

In the public sector, Fuss & O’Neill, Inc. and Fuss & O’Neill EnviroScience, LLC have been awarded Government Services Administration (GSA) schedules to provide engineering and environmental services to federal agencies.

While we continue to grow, expanding both our geographic presence and areas of expertise, our values have not changed. We seek clients and employees who value integrity, quality and professionalism; and believe that the success of our clients is inextricably linked to that of Fuss & O’Neill.
