Law Offices of Jonathan M. Cooper


"I appreciate what you have done and your online information is a boon to the average citizen." - B.W.


I first met Jonathan several years ago when we represented co-defendants in a products liability case.  Jonathan quickly impressed me as a savy strategist and a vigorous and thorough advocate.  He was a tough adversary, but was collegial, and we worked constructively on behalf of our respective clients.  Jonathan hits hard on the issues, but is fair and courteous to his adversaries.  As dedicated as Jonathan is to his profession, he impresses me most because he places faith and family first.

Jonathan is brilliant, diligent, aggressive, and ethical which is why I do not hesitate to refer clients and other lawyers to him.  Jonathan meets or exceeds the toughest expectations.

I had the pleasure of working with Jonathan on some appeals and complex motions several years ago, and found him to be a highly skilled and very professional attorney.  He is tireless in his efforts to obtain the best possible results, and takes great pride in his work, as he should. He is an excellent researcher and a gifted writer. And, he is of the highest moral and ethical character.  I recommend Jonathan Cooper without hesitation.

Jonathan not only got us the result we wanted; he exceeded our expectations. Jonathan's pedal-to-the-metal drive makes you feel that your case is equally important to him as it is to you.  He uncovered a novel and great argument to win our case,  and wasn't afraid to go toe-to-toe with some very nasty attorneys that had sued us; In fact, I got the impression that he enjoyed the challenge. On the whole, Jonathan pursued our case aggressively and intelligently, and was responsive to our questions. He remained confident even when things looked bleak to me. Although I did not know what to expect when I hired Jonathan, and this was my initial experience with litigation, my wife and I are happy we hired Jonathan. He is exactly the kind of lawyer you want, and we not hesitate to hire him again.  December 12, 2007
