What KPRG and Associates does
KPRG and Associates, Inc. is a 12-person environmental consulting and remediation firm that operated as a regional Midwest practice serving energy, industrial, real estate, and municipal clients in Illinois and Wisconsin. The company was incorporated in Indiana in 1993 and has operated under the KPRG brand since 2004, delivering a portfolio of services that includes environmental compliance and permitting, site investigation, development of remedial alternatives and remedial design/construction, expert witness and litigation support, environmental evaluation and reporting, and asbestos and mold assessment.
The business is a project-based professional services firm: revenue is generated through individually quoted engagements rather than standardized pricing, and delivery is performed by a small bench of credentialed practitioners — including Principals Tim Stohner, PE and Mark Wilson and Technical Directors Frank Santella, PG and Patrick Allenstein, PG — under the ownership of co-founder and majority owner Rich Gnat, PG. Distribution is direct enterprise and government field sales, with no channel partners, software products, or recurring platform revenue components.
In June 2026, KPRG was acquired by Roux, a national environmental consulting and management firm. At acquisition, the Brookfield, Wisconsin office became a satellite of Roux's Oak Brook, Illinois operations, and KPRG's principals, technical directors, and client relationships were integrated into Roux's Midwest platform. No transaction terms or prior-period revenue figures were disclosed.
