  • Managing the full range of litigation against OSHA, including appeals of citations, negotiations of settlements geared to minimize the impact of enforcement actions on wrongful death and personal injury civil cases, and trials before the OSH Review Commission.

  • Representing employers during U.S. Attorney criminal investigations and prosecutions of alleged OSH Act criminal violations.

  • Advising employers’ other attorneys in civil cases stemming from workplace accidents about the overlapping OSHA regulatory issues.

  • Counseling clients through catastrophic industrial, construction, and manufacturing workplace accidents, including explosions and chemical releases.
