Handling Serious Cases Against Heavy Industry

We Handle Toxic Exposure, Asbestos, and Fela Claims

A Unique Advantage: Knowing the Corporate Defense Playbook

What sets Attorney McMahon apart in the complex field of toxic tort and personal injury law? Over 15 years ago, he started his career representing the very corporations he now fights against.

This extensive background, built over a decade and a half and involving thousands of cases from the defense side, gives our clients an invaluable and unique advantage. Gregory is not guessing about the opposition's strategy; he implemented it daily.

He brings a deep, insider understanding of:

  • The legal tactics and maneuvers corporate defendants use to delay or deny claims.
  • The types of evidence and weak points that are most vulnerable to attack.
  • The strategies employed to minimize the value of a victim's suffering.

Our team uses this hard-earned knowledge to anticipate and effectively counter corporate strategies, thereby putting our clients in the strongest possible position for successful negotiation or litigation. 

Over the last four years, Gregory has dedicated himself to prosecuting claims solely on behalf of victims, bringing a powerful perspective to hundreds of plaintiff cases. When you hire our firm, you are turning a former defense attorney’s proficiency directly into an asset for your family’s justice.

Our Commitment: No Fees Unless We Win

We believe that every victim deserves top-tier legal representation, regardless of their financial situation.

  • Contingency fee basis: You will not pay any attorney’s fees unless we successfully secure compensation for you through a settlement or verdict. This means you incur no out-of-pocket risk by hiring our firm.
  • Complimentary confidential consultation: Your first step is without risk - a free, no-obligation consultation to discuss the facts of your case and learn how we can help.
