Representative Matters

  • Represented a client in multi-party mediation and pretrial sessions as both its workers’ compensation defense and subrogation counsel. The injured worker alleged medical malpractice following a work-related cervical fusion that left her completely incapacitated. The Injured Worker was receiving 24-hour in-home care and the client’s future exposures on this case were over $7 million dollars. Through an aggressive defense and universal approach, Brian resolved the workers’ compensation case for $1.00 alongside a waiver of its workers’ compensation lien.
  • Represented a Chicagoland landscaping company in a workers’ compensation case involving a claim for medical bills of over $350,000.00 and future cervical fusion. Through extensive investigation, Brian uncovered the petitioner had used a false identity and filed a second workers’ compensation claim against another employer with a different name, butsought an award for many of the same medical and indemnity benefits. Brian secured an Arbitration and Commission decision that denied, the petitioner all benefits in his case. The facts of this case were so compelling it has been used as part of Arbitrator and Commissioner training at the Illinois Workers’ Compensation Commission in years since.
  • Filed a civil complaint on behalf of a client acting as the subrogee of an injured worker seeking recovery of workers’ compensation benefits paid by the client to the injured worker. The injured worker had previously dismissed his lawsuit against the alleged at-fault party, so Brian received the referral just before expiration of the statute of limitations. Brian survived a motion to dismiss filed by the defendant and prosecuted the claim, leading to a recovery of nearly the full amount of benefits paid in the workers’ compensation less than a month before a jury trial was set to begin.
