“I would like to commend Atty William E Parsons and Hawks Quindel, S.C for fighting for the reinstatement of my benefits that my work insurance company cancelled on me. Bill fought long and hard for my benefits. He always answered my questions in a matter of minutes, no matter what day they were on, even weekends. He also allowed a 3rd party conference call, when he had news for me. I look forward to seeing his success with this firm and would highly recommend him at your attorney… He gets the job done.”
