Andrews & Anderson Architects was founded in 1990 in Golden, Colorado by Nan Anderson and Deborah Andrews. Dave Anderson joined in 1992. Deborah left the firm in 1996 to pursue new interests. In 2011, long time employee Liz Hallas became a principal, at which time we became Anderson Hallas Architects. In 2015, Wells Squier joined the leadership team completing our second generation of partners.

Today we are an architectural firm committed to community-based public sector work. Our contemporary design services complement our national reputation in historic preservation.
