About Us

Whether the project is small and straightforward, or large and complex: whether it requires single or multiple design disciplines: Fuss & O'Neill provides the solutions that clients need for their specialized projects.

Founded in 1924, the company has grown to encompass six regional offices, six LLCs and about 300 employees. Our staff includes professionals that are actively involved in professional organizations and who maintain licenses and certifications across a breadth of scientific, engineering, design build and manufacturing disciplines.

Our full service capabilities continue to expand as we participate in the Green Revolution. We are corporate members of the United States Green Building Council (USGBC) and have over 20 certified Leadership in Energy and Environmental Design Accredited Professionals (LEED-AP). Fuss & O'Neill is also actively involved in the Congress for the New Urbanism (CNU), a partner with the USGBC. In the public sector, Fuss & O'Neill EnviroScience, LLC was awarded a Government Services Administration On-Call (GSA Schedule) to provide Environmental services to Federal agencies.

While we continue to grow, expanding our regional presence, innovative technology and across-the-board services, our values have not changed. We seek out clients and employees who value integrity, quality and professionalism. We establish client relationships based on long-term partnership, respect and solid communication, and we firmly believe that the success of our clients' projects is inextricably linked to that of Fuss & O’Neill.
