Founded in 1989 by Donald Jensen PE, Jensen Design & Survey, Inc. is the largest engineering firm headquartered in Ventura County. Prior to this, however, the Jensen name had already built a great reputation in the Ventura area - Bill Jensen, Don's father, ran an engineering firm in Ventura from 1961-1997.

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 in the state of Alaska. These vast experiences, combined with the local-area name recognition, have allowed Jensen Design & Survey, Inc. to become the premier leader of civil engineering services in the Ventura County area. In addition, Don's wife, Lynn Gray (a Registered Geologist) assists the company and as Chief Operating Officer.

Originally a small handful of people, our staff has now grown to over forty educated and experienced professionals. We are proud of our staff and the wide range of expert services that we are able to provide.
