Client
Very experienced. Very educated. Would definitely recommend these guys.
Client
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 knowledgeable. My questions are answered in a timely manner.
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.
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.
Client
Thornton Law Firm gets the full five stars rating with me. Whenever I communicated to them with a question I was either answered right away or I was referred to the right person to ask. I received settlement checks that were correct and processed with banks easily. The lawyers were a pleasure to talk to, especially Michael Thornton who I was fortunate enough to meet in person.
Client
Caring, thorough and extremely competent - this firm did an excellent job in handling my case. I would recommend them to all.
