Jay is a great attorney with decades of experience. His fees are comparable to others of his caliber. He is also a good person. Smiles alot, except when he needs the teeth of a pit bull. You can count on Jay!

Jay is an excellent, courtroom savvy trial attorney. Very aggressive, knowledgeable and committed. I am also a trial lawyer with many years experience and I have seldom, if ever, watched a better lawyer ply his trade.

Jay is not only an outstanding lawyer, he is a wonderful person. In the several times I have asked for advice he has given the best legal advice he could gives his clients and the best personal advice a friend could give. It is never about the money with Jay, but the quality of life he gives his clients. More than worth the money. Even more for the advice legal and personal.

He was located in Mokena, Illinois when I used his services. He was short-tempered & was angry alot towards me. He seemed to be on my ex-husband's side. Also, very expensive for the terrible service I received for myself & my children!

He is very unethical. He knew my dad was mentally ill and took advantage of him. I've heard from family members that he is not a lawyer you want. Avoid his practice as you are going to overpay. In his own words "your dad needs to get himself into the hands of a professional". From that moment he kept him as a client and just went through the motions. Yes, he did have to deal with some crazy people. But he bought a property to sit there and do nothing.
