WOULD NOT RECOMMEND !

Some words I would use to describe after hiring Jennifer Thompson would be: unprofessional, incompetent, unstable, unprepared, and short tempered. For reference, she was my attorney for the first half of my divorce, and if you have the option to choose anyone other than Attorney Thompson, I would re...commend you do so and not make a tough time in your life any harder than it is already. The lawyer I hired after parting ways with Ms. Thompson was night and day difference in how they operated and so was my overall experience. If you're looking to get cussed out and screamed at by someone you're paying hundreds of dollars an hour to, Attorney Thompson is for you! Another big red flag I saw after the fact was when she showed up to court in a beat up looking Ford Escape. She complained about the Judge enough to me that I was convinced the Judge did not like her, which I don't think is a very favorable trait. Not sure if she had other issues going on in her life when I had hired her, but I don't wish anyone to have the type of experience I had with her. Two thumbs down, if I could rate her ZERO STARS, that would be more accurate than the 1 star. An absolute disgrace.

Seek other counsel

I considered and still am considering sueing Jennifer for her negligence in my case. I agree with the other reviews, she's incompetent and emotional and comes off as kind of cuckoo in front of the judge. The other party didn't even really have that good of a lawyer but she just chokes. She was tota...lly unprepared to fight for me, but super aggressive when trying to collect her pay. I lost everything because of her and am still in debt. I would advise anyone to seek other counsel.

Drops the ball

She's known in the fox valley for dropping the ball on her clients. I'm not sure what these people hired her for but she wasn't aggressive or fierce. She coward at every turn. I got completely screwed because of her. Hire manske or hertl, she can't stand up to either of them.

Aggressive and knowledgeable!

Attorney Thompson handled a complicated family matter for us, and she gave 110% from day one! Our case took over two years to conclude, and she never stopped fighting for us despite all the games the other side played. I would highly recommend her to anyone looking for an aggressive attorney!

Consistent, Confident, and Reliable

Attorney Thompson and her firm have been assisting me with my divorce case for about eight years. I have never considered using anyone else to help me with my continual and complex issues. I feel Attorney Thompson has always been consistent, confident, and reliable for me, and my best interests as a ...single father.
