History

Founded by F. Beach Leighton in 1961 as F. Beach Leighton and Associates (FBLA), the company started out of his own home-office providing just engineering geology with a staff of only seven part-time employees.

To better serve clients and for improved quality control of the geotechnical reporting, Beach decided to expand the firm's services to provide soils engineering. In 1972, Beach did this by establishing a new company that became the soils engineering arm of FBLA. In the same year, Beach formed another company that was devoted to applying geological sciences and soils engineering to environmental planning. By 1974, all three companies merged into one celebrating its new name, Leighton and Associates, Inc.

Over the past 37 years, several subsidiary companies were formed to extend specific services to the individual needs of our growing clientele and dynamic market sectors. Today, we have evolved into Leighton Group, Leighton Consulting, and Leighton and Associates.

Proud of our valued heritage, Leighton is committed to continually providing the highest possible delivery of services and providing you, our clients, with solutions you can build on.
