About Opsahl Dawson

We’ve completely reinvented the accounting profession: Traditional values, cutting-edge technology, and first-class service.

President of Opsahl Dawson, Aaron Dawson, and founder, George Opsahl, share many things in common. Both…

  • Born in Longview, Washington
  • Left home to study accounting
  • Began their careers in the big city of Seattle
  • Returned to Longview to embrace a community better suited to raising families
  • Share a commitment to providing excellent client service
  • Know that integrity is the only thing that stands the test of time

Today, Opsahl Dawson is flourishing. We know that our company is only as good as its employees. Our relentless pursuit of excellence drives the effort of training and recruiting top professionals from the best schools in the Pacific Northwest.
