Cornerstone Design-Architects began as W.N. Marsh Associates Ltd. Architects in January of 1990, in affiliation with 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.

In May 2007, a new chapter was started as Cornerstone Design-Architects underwent an ownership restructuring, with a goal of providing even more dedicated levels of client commitment. In November 2007, the firm moved its corporate offices to 48-50 West Chestnut Street, Lancaster PA. Today the story continues to grow.
