Thorburn Associates, Inc. is a design and engineering company founded in 1992 by Lisa A. Thorburn and Steven J. Thorburn. Providing services for architectural clients in the areas of acoustical consulting and audiovisual technical system engineering, TA is a single point of contact during design and construction.

By 1995, TA had more than tripled in size and moved from its original offices on Hillcrest Avenue to an office in Castro Valley, California.

In the Fall of 2001, TA moved again to larger offices in Castro Valley (our present location).  We now employ a staff of engineers, designers, drafters, technical assistants and support staff in the main office, with  branch offices in Los Angeles, CA, Raleigh-Durham, NC and an associate in Boise, ID.

With the expansion of services and top quality support our continued growth is assured.  The firm's success is rooted in our belief of close cooperation and adherence to the highest professional ideals.
