Roy F. Weston

Roy F. Weston was a proponent of environmental engineering and a visionary of “sustainable development” long before this term became a popular catchphrase. In 1957, he founded Roy F. Weston, Inc., (Weston®), initially focused on wastewater treatment, and quickly thereafter recognized as a groundbreaking environmental engineering firm.  Weston was one of the first to handle cleanup of hazardous sites after the U.S. government established the Superfund program in 1980.

Weston grew substantially over the years, increasing the breadth of its service offerings through organic internal growth and small strategic acquisitions. In 2001, the company became the employee-owned Weston Solutions, Inc. that it is today.
