Your New York State Defense Partner Since 1991
Celebrating our 30th Anniversary!

Gone are the days of handling only hearings and appeals. As the WCL landscape has changed, we have been at the fore, working with our clients, the Board, industry, bar groups, and legislators to shape the discussion and provide a full spectrum of legal services in the workers' compensation arena. These include:

  • Defense of claims from initial file review through trial and summations
  • Section 32 settlement negotiation and preparation
  • Calculation and submission of Medicare set-asides (MSAs)
  • Handling conditional payment recovery demands
  • Loss Transfer arbitrations
  • WCL Section 120 discrimination claims
  • Research projects for clients on major issues affecting workers' compensation
  • Statewide appellate practice before the Board, Appellate Division, and Court of Appeals of the State of New York
