Originating in 1955 as the T.C. Biebesheimer Engineering Company, the firm later evolved into Mannik & Smith, Inc., focusing mainly on highway and bridge design. In the 1980’s, the company added environmental services to compliment its civil engineering capabilities and created Midwest Environmental Consultants. The two companies merged in 2000 and now operate solely as The Mannik & Smith Group, Inc. (MSG). In 2006, MSG merged with the former Braun-Prenosil Associates, which now operates as MSG’s Northeast Ohio Office.

MSG is a full-service engineering consulting firm that offers a wide array of services including civil and geotechnical engineering, environmental consulting, surveying and construction support.
