Garmann Miller Acquires Access Engineering Solutions

GM adds in-house civil engineering to enhance its multi-service offerings

MINSTER, Ohio— Garmann Miller, a multi-service facility design and planning firm, has acquired Access Engineering Solutions, a civil engineering company in Celina, Ohio, effective March 31, 2025. Access Engineering will now operate as a member of the Garmann Miller family of companies, which also includes Lancaster, Pennsylvania-based Gilbert Architects.

“Access and Garmann Miller are well-aligned culturally, making this acquisition a natural next step,” said GM CEO Eric Baltzell. “With a proven track record of growth and success, Access enhances our ability to deliver comprehensive, integrated solutions to our clients.”

Founded in 2013, Access Engineering Solutions has built a strong reputation in the municipal, utility, and roadway sectors. As longtime partners, the firms have successfully collaborated on several projects, including recent work with Celina City Schools, Marion Local Schools, and New Bremen Local Schools.

“We’re excited for this partnership, which brings together two firms that share a strong commitment to quality and service,” said Brice Schmitmeyer, Access president. “Having worked with GM on many projects, we’ve seen firsthand how well our teams collaborate to provide innovative solutions.” 

Access will continue doing business under the Access Engineering Solutions name and will maintain its municipal project work while selectively contributing civil engineering expertise to Garmann Miller’s portfolio throughout the Midwest and Mid-Atlantic regions.

This acquisition reflects Garmann Miller’s strategic commitment to expanding its in-house services and strengthening its integrated project delivery model across the regions it serves.
