Tri-Lake Consultants joins Interwest

In April 2018, we acquired Tri-Lake Consultants, a Public Works and Engineering firm established and respected in the Inland Empire for over 30 years. We welcomed 17 talented employees and three new clients: the City of Perris, City of San Jacinto, and March Joint Powers. We were able to increase our capacity to provide services in this region of California as a result of Tri Lake joining our family. An added benefit was a well-established office in Perris, California, where we continue to grow our client base and provide services.
