Our History

The law firm of Cousineau Waldhauser Kieselbach, P.A. (CWK) may have incorporated in 2016 but our lawyers are part of a rich legacy of dedicated and client-centric professionals that began nearly 70 years ago.  In 1948, Roy Mordaunt, an experienced litigator, and his son established a new law partnership in the Twin Cities, Mordaunt & Mordaunt.   The firm’s commercial practice included both civil litigation and workers’ compensation.


Henry Cousineau and Robert McGuire, two highly influential and respected lawyers (and our predecessor firm’s founding partners), joined Mordaunt & Mordaunt in the late 1950s, and in 1972 the firm became known as Cousineau, McGuire, Shaughnessy & Anderson.  By this time two distinct practice groups had emerged:  the Workers’ Compensation Group and the Civil Litigation Group.  The firm adopted the name Cousineau, McGuire & Anderson Chartered in 1990 and was rebranded Cousineau McGuire Chartered in 2005.


Many of CWK’s lawyers, including two of its named partners, spent virtually their entire legal careers building and nurturing the Workers’ Compensation practice group at Cousineau McGuire.  Jim Waldhauser joined the firm in 1978, and Tom Kieselbach, CWK’s president, joined in 1980.   John Thul, Mark Kleinschmidt, Tom Coleman, Dick Schmidt and Lisa Kinney each practiced in the Workers’ Compensation Group for over twenty years.


In 2016, after much deliberation and consideration of the interests of our clients and staff, the two successful practice groups at Cousineau McGuire decided to split into two firms.  The Civil Litigation Group became Cousineau, Van Bergen, McNee & Malone, P.A., and the Workers’ Compensation Group became Cousineau Waldhauser Kieselbach, P.A., with each firm retaining the Cousineau name, reputation for excellence, and many good memories of our years together.

Litigation Highlights

Ryan v. Potlach — A Win for Cousineau McGuire at the MN Supreme Court


Cousineau McGuire attorneys Natalie Lund and Jim Waldhauser successfully represented a Self-Insured Employer at the Minnesota Supreme Court in Ryan v. Potlatch Corporation. The decision from the Minnesota Supreme Court was issued July 13, 2016, and changes the law with respect to the closure of future consequential injuries in a Stipulation for Settlement. Prior to Ryan, the Workers’ Compensation Court of Appeals held for decades that future unknown consequential injuries could not be closed out in a Stipulation for Settlement. As such, an employee who claims a consequential injury arising after a settlement could merely file a new Claim Petition. A Petition to Vacate would not be necessary, and the employer and insurer would not get a credit for any benefits paid pursuant to the prior settlement agreement. This would allow an employee to obtain a double recovery of benefits. The WCCA upheld this precedent in Ryan, and Ms. Lund and Mr. Waldhauser appealed.


The Minnesota Supreme Court reversed and remanded, agreeing with the Self-Insured Employer that the WCCA had misconstrued the Supreme Court’s decision in Sweep v. Hanson Silo Co. Further, the Court agreed that Minn. Stat. 176.521 allows the parties to settle any claim for compensation, which includes future consequential injuries. The proper procedure for a consequential injury claim after a settlement is to file a petition to vacate.
