The Sigma Group is pleased and excited to announce that Rivers Bend Engineering and The Sigma
Group are embarking on a new partnership. While we have a great history of collaboration on
numerous projects, we have decided to further our teaming opportunities by merging our firms.

Both Rivers Bend and Sigma have a common objective of providing excellent service to support
our clients’ success and add value to their organizations. We are both committed to problem
solving utilizing our creativity, technical expertise, and extensive experience.

Rivers Bend Engineering’s dedicated and experienced professionals expand on Sigma’s portfolio
of civil engineering, environmental engineering, geoscience consulting, and facility consulting
services. Their technical skill set enhances Sigma’s process engineering services, particularly in
the field of industrial wastewater treatment, industrial process design, and control systems. For
those organizations and clients whom we serve, this merger broadens our geographical reach
with Rivers Bend Engineering staff continuing to operate out of Racine, Wisconsin office, and
supplemented by Sigma’s Milwaukee, Wisconsin headquarters. While our talent and skill pool is
growing, more importantly, the merger brings access to more resources to those we serve.
