    About Us


    Our Approach

    We are in the business of making the recovery process as easy as possible for you.  After you retain Mr. McMahon, he communicates with the insurance companies and completes any necessary paperwork on your behalf, so that you don't have to.  At the same time, attorney McMahon relentlessly pursues your case with the insurance company, and then, if necessary, in court.
