About Us


Improving the Quality of Life

At LJB, our chosen professions include civil, structural and safety engineering as well as environmental sciences, survey and architecture. But just providing these services isn’t enough.

We challenge ourselves with the question, “Why exactly are we doing this?” And the answer lies in the core purpose LJB was founded on nearly 50 years ago—improving the quality of life. This may seem like just a brand tagline, but it drives our day-to-day behaviors.

Since 1966, LJB Inc. has been improving the quality of life for our clients, our people and the communities we serve. The firm’s founding partners—Bill Lockwood, Harold Jones and John Beals—had a passion for the highest level of design and a vision to fulfill the needs and dreams of our clients. They created a lasting culture that fosters innovation and attracts high achievers, creative thinkers and great communicators.
