After working in the Chicagoland market for years, Henneman Engineering opened its Chicago office in 1999.  The office was headed by Al Raufeisen and staffed with other experienced engineers who transferred from the corporate office.  In 2003, Jeff Treiber, P.E., joined the firm as Senior Vice President and serves as Director of the Chicago office.  

The Chicago office works seamlessly with other Henneman offices through a shared network and video conferencing.
