Columbus, OH – March 20, 2026 – T&M Associates, a leading engineering and technical services firm, proudly marks its 60th anniversary, celebrating six decades of engineering excellence, trusted client partnerships, and a deepening legacy of environmental leadership and community impact in Central Ohio and across the Midwest.

Founded in 1966, T&M has grown from a seven-person firm into a multidisciplinary organization of more than 375 professionals serving public and private sector clients nationwide across five core markets: Buildings & Facilities, Community and Land Development, Environmental, Transportation, and Water. The firm established its Midwest Regional Headquarters in Columbus in 2012, underscoring a long-term commitment to supporting the region’s infrastructure, environmental, and community needs.

“This milestone is a testament to the dedication of our employees, the loyalty of our clients, and the strength of the values this firm was built on,” said Gary Dahms, President and CEO of T&M Associates. “As we honor our past, we’re equally focused on shaping the future — delivering sustainable solutions, strengthening communities, and continuing to push innovation forward.”

Honoring the Past, Shaping the Future
Drawing on six decades of experience, T&M brings a practical, long-term perspective to the complex challenges facing the City of Columbus and the surrounding region. The firm has played an integral role in major environmental initiatives and critical water, sewer, and stormwater infrastructure projects – helping communities modernize essential systems while preparing for future growth and climate impacts.

“Our longevity is rooted in our culture and our commitment to doing what’s right for our clients and communities,” said Patrick Jeffery, Chief Operating Officer at T&M. “That same mindset fuels a culture of innovation – driving us to continually evolve, embrace new technologies, expand our capabilities, and plan for the long term.”

Community Impact Through the T&M Foundation
T&M’s presence in the Columbus region extends beyond project delivery to a deep commitment to public service and community engagement. Through the T&M Foundation – celebrating its fifth anniversary in 2026 – the firm supports charitable outreach, STEM education, and volunteerism. Through the Foundation, employees support local organizations, including the Star House and Open Shelter, and partner with the Barnett Community Center to provide youth programming, educational gardens, and enrichment opportunities. The Foundation has also established Ohio State University engineering scholarships for women and minority students, helping strengthen the region’s future workforce and expand access to STEM education.

This work has earned T&M recognition from leading industry organizations, including prestigious engineering excellence awards and repeated workplace culture honors, such as Best Workplace in Ohio distinctions and multiple awards for corporate citizenship and community stewardship.
