S3E Engineers and its predecessors have provided engineering services since 1963.  

Originally known as LBC&W / Maguire Group, an internal ownership transition in 1989 created S3E as independent consulting engineering group maintaining the same staff and location.  

S3E and Klingemann Consultants merged in 1998.  

S3E Engineers and its personnel have performed engineering services on many institutional, public, and private projects throughout the United States and Canada. We specialize in projects with complex technical and coordination requirements.
