Gruen and her husband, Claude Gruen, joined ULI in 1971, not long after founding Gruen Gruen + Associates, a renowned San Francisco–based firm that continues to provide research-based consulting and implementation services to the real estate industry and public land use and planning policy makers. Gruen, who remained active in ULI throughout her career, was elected as the Institute’s first female trustee in 1982, and was named an honorary member in 1996.
