Cornerstone Design-Architects has grown into a cutting-edge, yet client-driven design firm during its 17-year history. Originally incorporated under the name of W.N. Marsh Associates Ltd. Architects in January of 1990, as an affiliate of The Horst Group. In February of 1995, the company name was changed to Cornerstone Design Ltd. Architects. In January 1997, Dale R. Yoder, AIA, was named President and in June 1997 became a fifty percent owner of the firm. In May 2007, Cornerstone Design-Architects began a new era of employee ownership with a goal of providing even more dedicated levels of client commitment. Buying out Horst Group's 50% share of ownership, the four managing partners now include Dale R. Yoder, A.I.A. President; Rick Walker, A.I.A., C.C.S., Vice President; John O. Yoder, III, A.I.A., Director of Design & Construction Services; and Julie R. Parker, Business Manager. The firm moved its corporate office to 48-50 West Chestnut Street in November 2007.
