Our Main Goal Is Your Satisfaction.

I have been a client for many years. Whenever I have a question or problem, I call. The persons I have spoken with are professional and knowledgable. My questions are answered in a timely manner.

Cheryl D.

Client

The attorneys were very compassionate in dealing with my dad who was suffering from mesothelioma. They came to our home to carry out a deposition and went right to work carrying out justice for him. They have worked diligently to help our family. I would recommend them to anyone looking for a law firm. Everyone I have dealt with was professional and kind.

Deb L.

Client

As a plaintiff, I had the opportunity to partner with Mike Lesser and the Thornton Law Firm on a rather complicated civil case which involved 15 defendants on one side and the federal and state governments with me on the opposite side. I could not have been more favorably impressed and satisfied with Mr. Lesser and his firm’s professionalism, competence and results. I highly recommend him and his firm without reservation.
