Alexander & Associates, Ltd was founded by principal architect, Joseph D. Alexander, AIA in 1978. Joseph worked for several years out of an office space in Northfield, Illinois. Within three years, the firm grew to three employees and the office moved to a larger space in Northbrook, where it remained for 23 years. It was in the Northbrook office that Alexander & Associates, Ltd. became known as one of the premier architecture firms for building restoration. As the firm's work grew within the City, it became advantageous to move the office from the north suburbs to the Chicago Loop. Alexander & Associates, Ltd. has been at its current location at 11 E. Adams Street since 2005.
