About Iron Horse Builders LLC


Founded in 1972 by Bill Mosmeier, a civil engineer and farmer who combined technical expertise with deep faith and service to his community. Bill’s vision was to build a company where family values and quality craftsmanship guided every project.

A Legacy of Family Leadership

After Bill’s passing in 2001, Chris Mosmeier took over, expanding the company’s focus beyond agricultural buildings toward customized residential and commercial structures. The company continues today as a third-generation operation, with Keifer Mosmeier, a University of Cincinnati civil engineering graduate, bringing fresh expertise, alongside a skilled team of long-term craftsmen and equipment operators.

Our hands-on family involvement ensures that every project receives meticulous attention and accountability.
