Harmsen is experienced working in rural areas, towns, and large metropolitan areas.

Harmsen was founded by Bill Harmsen in Monroe, WA in 1974.  Through various acquisitions, we have extended our expertise and service areas via offices in Oak Harbor, WA in 2007, Mount Vernon, WA in 2011, and in 2016, Alpha Subdivision Professionals, Inc., in Everett.  These acquisitions have augmented Harmsen's rich survey records archive with those of Leonard, Boudinot & Skodje, Fakkema & Kingma, Inc., Meriwether Leachman Associates, Inc., and Evergreen Surveying, Inc.

We are passionate about helping others succeed
Harmsen engineers, surveyors, planners, and skilled office staff are absolutely the key to our success. Our aim is to provide the highest level of value to our clients and business partners.  Our ability to accomplish high value work is manifested through our extensive set of repeat contracts for private and public entities.
