Significant Representative Matters

  • Successfully defeated a claim petition for an alleged work-related heart attack.

  • Defeated a claim petition for psychological injuries involving an employee who also had a discrimination matter pending in federal court. 

  • Defeated a review petition which alleged that the description of injury should be amended to include depression and post-traumatic stress disorder when the claimant had been out of work for a physical injury since 1989. 

  • Obtained successful decision in a funded employment case for a long-time 1992 cognitive dysfunction injury. Proved that a position created for claimant through a different employer, but for which the salary was going to be funded by the employer, was within claimant's restrictions as set by an independent medical evaluator. Able to discredit on cross examination claimant's long-time treating psychiatrist. The Workers' Compensation Judge granted our modification petition based on salary that claimant would have received had he accepted the position. 

  • Defeated a claim petition for benefits filed in Pennsylvania, despite the employer being headquartered there, persuading the judge that there weren't enough significant contacts to bring it into Pennsylvania jurisdiction.
