Great Lawyer

I hire Jason Marker after sustaining a workplace injury, and not receiving fair treatment. Jason and his team were professional and always accessible regarding any questions or concerns I had. He kept me informed of the progress on a regular basis. Thank you

Excellent experience

I was referred to Mr. Marker by a coworker after getting injured at work. I contacted the firm through their website and received a response within an hour and after the initial exchange of information a meeting was set up with Mr. Marker. My wife and I entered this meeting confused and not knowing ...what to expect. Mr. Marker was very friendly and put us at ease with a careful explanation of Illinois work comp laws, how my specific injury was covered by these laws, what to expect in a settlement and the time-line ro expect it in. We retained the firm and left feeling confident and informed with an idea of what to expect. Mr. Marker called several time to inform me of the cases progress and consult with me once a settlement offer was put forth by my employer. My options were discussed and he recommended a reasonable counter offer that was accepted by my employer. We were very pleased with the outcome and felt that we were well represented by Mr. Marker and would recommend him to anyone involved in a work comp case in Illinois.
