Company History

CHS Engineers was founded in 1992 by Scott Christensen, Tim Harrigan and Andy Soulé, all professional civil engineers with extensive experience serving cities, towns and special-purpose districts in western Washington. Starting with a staff of seven in January 1993, CHS has grown to a team of 26 engineers, surveyors, inspectors, technicians and administrative staff. We continue to serve the same Clients that we started with over a decade ago, and have added numerous public and private entities to our list of satisfied customers. Andy Soulé retired in 2001 to move out of state. Tim Harrigan's retirement in 2004 coincided with bringing Rodney Langer, Evan Henke and John Nottingham on as Principals with Scott Christensen. In April of 2005, CHS Engineers merged with The McAdrews Group to broaden and strengthen the services each company offers. This merger brought Larry McAndrews on as a fifth Principal. Together the five working owners of CHS offer over 90 years of combined experience to respond to the challenges facing our municipal and private Clients.
