About Us

Hi, we're twin sisters Jacqueline and Kathleen Byron. We were born in Aberdeen, WA and raised in Hoquiam. We graduated from Hoquiam High School in 1982, then went on to study engineering at Grays Harbor College, the University of Washington, and St. Martin's University. In 2007 we formed Byron Engineering, PLLC. We both have over 20 years of engineering experience.

In addition to engineering, we also design websites and provide technical services including computer aided drafting, graphical design, and custom VBA programming. Visit our Byron Tech website for more information on these services.
