The Founders
WHKS & Co. began in 1948 as the Wallace Engineering Company in Clear Lake, Iowa. The office moved to Mason City the following year.
In 1956, the Company became known as Wallace and Holland when Francis Holland joined as a partner with Ralph Wallace. In 1964 Frank Schmitz and Dick Kastler became partners and the name was changed to Wallace Holland Kastler & Schmitz.
In 1994, the shareholders changed the Company name to WHKS & Co.
Shaping the Community
In 2021, WHKS was named the Flagship Investor of the year for the North Iowa Corridor Economic Development Investor campaign. The North Iowa Corridor’s annual campaign generates private investment to complement public funding it receives from the City of Mason City, Cerro Gordo County, and the City of Clear Lake. Investors help the corridor promote the region, develop business recruitment and retention, and improve workforce development.
Here at WHKS, we recognize that economic development is the key component in the health of the communities that surround us. We strive to continue pushing communities forward and driving future growth.
