Parametrix was founded in 1969 by Waite Dalrymple and George Capestany as Delta Engineering. Originally focused on
the wastewater business, the firm grew quickly and diversified into six very different business divisions. In 1974, two of
the divisions, Delta Engineering and Seattle Marine Laboratories were restructured as Parametrix. With strength in both
engineering and science, Parametrix became known as the premier firm for solid waste and city engineering in Washington.
Continued steady growth led to expansion into Oregon in 1989 with the opening of our Portland office which specialized in
solid waste and environmental remediation to start. One of the office’s first projects was the St. Johns Landfill closure.
In the early 1990s, the owners began considering transition options, and determined that becoming an ESOP would allow
the company’s culture to remain intact and provide a secure future for the employees and their families. Parametrix was
established as an ESOP in 1992, and through regular sales of the owners’ stock to the ESOP trust, became 100 percent
employee owned in 1999. Parametrix embraced employee ownership and in 2001 was named the “Employee-owned
Company of the Year” by the National ESOP Association.
Parametrix diversified into the transportation business in the early 1990s with the development of the master plan for the
Washington Coastal Corridor Scenic Byway along US 101. In 2001, Parametrix expanded into New Mexico with the opening of
our Albuquerque office, focusing on tribal and natural resource services in the Southwest. Expansion continued in 2003 when
our Boise office opened, focused on transportation. In 2008, we acquired Taschek Environmental Consulting in New Mexico
expanding into the cultural resources business. Today, Parametrix serves clients throughout the western United States from
offices in Washington, Oregon, Idaho, and New Mexico.
