Company History

Founded in 1989 by Donald M. Jensen PE, Jensen Design & Survey, Inc. (JDS) is the largest engineering firm headquartered in Ventura County.

Don Jensen’s background includes a Master’s Degree in Civil Engineering from the University of Alaska, as well as work experience as a civil engineer in the state of Alaska.
