Established in 1976 by Carl and Brainard Simpson as a Certified Public Accounting firm, Simpson & Simpson began providing construction management services to the County of Los Angeles in support of the reconstruction efforts after the 1994 Northridge earthquake.

In 2001, Simpson & Simpson Management Consulting was created as an independent entity to further expand the firm’s services into Program, Project and Construction Management. Today, Simpson & Simpson is a full-service professional management organization serving a variety of clients in Southern California.
