Architectural Resources Group (or ARG; also known as Architects, Planners & Conservators, Inc.) is a firm that was founded in 1980 by Bruce Judd and Steve Farneth in San Francisco, CA. It began by providing professional services in the fields of architecture and urban planning with particular expertise in the area of historic preservation. In 2000, David Wessel, a Principal of ARG, founded a separate conservation-contracting division, ARG Conservation Services which operates under the same roof as ARG. By 2005, the firm had expanded to a full-service architecture firm with 50+ employees. ARG also opened offices in Pasadena serving Southern California, and Portland, Oregon, serving the Pacific Northwest.
