Our History

threekingsStarted by Ronald Yohn in 1946 from a shell gas station, YohnCo

is enjoying nearly 70 years of business. Ron, along with John Schisel and Fred Grell began with two small gravel trucks and a dragline in Garner, Iowa. By the end of the year they had opened a Concrete Ready Mix Plant with two ready mix trucks, carrying a maximum of three yards of ready mix concrete each. By the 1960s Ron had bought out both partners and what was initially called Garner Ready Mix became Yohn Ready Mix.

Lil-JohnIn 1954 the company expanded to Belmond, Iowa, Forest City, Iowa in 1957, and in Clear Lake, Iowa in 1973. Clear Lake is where the corporate office is now located. At one time there was a YohnCo plant in Buffalo Center, Iowa and there is now a portable plant located in Clarion, Iowa.

In 1972 Ron's son, Bill Yohn bought the company and has continued to develop it into the company it is today. Eight years later, YohnCo acquired a construction company that specializes in poured footings and wall foundations. YohnCo also includes two excavation companies that specialize in private development, as well as county, municipal, and state excavation projects. In 1990, Bill Yohn purchased Wright Materials, a sand and gravel operation located in Belmond, Iowa, as well as locations in Cerro Gordo and Hancock Counties.

Yohn Co. Ready-MixToday YohnCo is being passed to its third generation. Laura Yohn serves as the quality control manager, and Alex Yohn controls the company's means of operation. YohnCo's fleet now includes twenty-five ready mix trucks, capable of hauling ten yards of concrete, nine multi-axle dump trucks. In 1946 the payroll covered seven employees, and today YohnCo employs fifteen full time and fifty-five seasonal men and women in Northern Iowa.
