Who We Are

Always Ready to Do It Right

Ritter Consulting Engineers Ltd. began in 1981 as Ervin Ritter and Associates, founded by Ervin L. Ritter, P.E. We adopted our current name in 1992 and have served clients throughout the Southeast from Lafayette, Louisiana, for over four decades.

During that time, we have built a reputation for dependable mechanical and environmental consulting services across the Southeast, providing experienced support to architects, engineers, building owners, and state and government agencies. Today, we are a full-service firm built on direct involvement and accountability. Each project begins with a clear scope of work catered to our client’s needs, continuing through design, documentation, and follow-up.
