SDG Associates

Sims Design Group Associates LLC, often simplified as SDG Associates, is an American architectural firm, headquartered in Detroit, Michigan, U.S.. It is the city of Detroit’s oldest Black-owned architecture firm.

History
It was founded in 1964 in Ann Arbor by architect Howard Sims, under the name Howard Sims & Associates. In 1968 the office was moved to Detroit. In 1969, the firm incorporated and Sims was given the role of president. Architect Harold Varner joined the firm in 1973. By 1976, the firm name was changed to Sims–Varner to reflect a new Varner partnership, and Varner as the executive vice president.

It now operates as SDG Associates. As of 2019, Wesley Sims (son of Howard Sims) is the CFO and COO of SDG Associates.
