Corporate History

SHA is a descendant of Rasche, Schroeder, and Sprancy, a firm that grew to prominence during the 1960s. The firm began in 1954 as Howard E. Schroeder Architectural. In 1977, after the departure of Rasche and Sprancy, Don Holt, the company’s first employee, was asked to become a partner and formed Schroeder and Holt Architects. SHA is currently led by David C. Baum, who has been with the firm since 1986.

A2K was originally established in 1993 by Robert L. Erdmann, Chuck Millmann, and Allen L. Weitermann. The company’s focus was on the design of elder care facilities and religious spaces. Once the original founders retired in 2004, David C. Baum became the new firm principal. Since that time, the firm has continued to build upon A2K’s reputation and experience in the design of safe, healthy environments for seniors and welcoming and empowering religious spaces.
