"I have been meaning to write this review awhile ago. Don doesn't just take your money and run, which most lawyers do. He was professional and highly recommend."

- Michael Zajac


"Don Cosley is the best D.U.I. and Criminal attorney in the Chicagoland Area. I was arrested in DuPage County with 10 serious counts including D.U.I. After firing my first attorney from the junk mail you get from lawyers after catching a case. I wanted to go the cheaper route. Like they say you get what you pay for. My first lawyer looked like he had no interest in my case did not give me any good vibes and was terrible in the court house. I had to fire him immediately. I remembered that I got great representation from Don Cosley years ago and I called him and I went to his office and he remembered me. After explaining my case I felt the relief and was convinced that he would fight hard to beat my charges. This man has integrity. He has an unbelievable presence in the courtroom, (And I now understand how crucial this is.) He stands for justice. He is fair. And, Don is an attorney that will FIGHT for you. I would pay this man his weight in gold because that is what he is in the courtroom: golden.” Thank you Don! You're the best!"

His approach to the situation is very professional. He is very knowledgeable of the family law, and very reasonable priced. I would highly recommend him if you need a family law attorney."
