The firm was established in 1956 when Lincoln F. Frelich, AIA, and James J. Angus, AIA became partners in the firm of Frelich-Angus and Associates in Janesville. The firm offered professional services in architecture and planning and was oriented toward institutional work. Lincoln Frelich received his degree in architecture from Illinois Institute of Technology; James Angus graduated from Princeton, and continued his graduate work at Illinois Institute of Technology. Roger Young, AIA, a graduate of Iowa State University, became a partner of the firm in 1972. The name of the firm changed to Frelich-Angus-Young Architects. This combination of principals continued until 1981 when Lincoln Frelich retired, and the firm became known as Angus-Young Architects, S.C. The firm of Angus-Young Architects was reorganized in 1986 by virtue of ownership changes, and became known as Angus-Young Associates, Inc.. The change included principal ownership by Gordon Buitendorp and James Vanderveen, owners of the architectural and engineering firm of GMB Architects/Engineers of Holland, Michigan. The expansion enabled the Janesville-based Angus-Young Associates to present a full range of architectural and engineering services and handle a variety of projects for their clients. In 1987, Jeffrey Hazekamp, AIA, joined the firm as the Managing Principal of the Janesville office. Joseph J. Stadelman, AIA, joined the firm in 1988 and became a principal in 1993. In 1990, Angus-Young Associates acquired the firm of Rose Associates/Architects. Between 1993 and 1997, Jeff and Joe acquired 90% of the firm from Mr. Buitendorp and Mr. Vanderveen of GMB. In 1997 the new principal ownership now in Wisconsin agreed to a working affiliation between the Michigan offices of GMB, Hooker DeJong, and Cash Associates. The affiliation brings the advantages of a large firm with a small firm economy and management. In 1997, Brad Heeres, P.E. became principal of the firm and subsequently was elected secretary and treasurer for the corporation. In 2004, Zachary Goswick, P.E. became principal of the firm.
