Our   Testimonials

D. Waters – Chicago, IL

Mr. O’Brien helped me with a difficult case where I lost my job and was unable to find other work.  This was very stressful on my family and Mr. O’Brien took the time to answer all of my questions.  My case ended up going to trial and Mr. O’Brien worked diligently and won a large verdict.  I am very thankful for the time and effort put in on my behalf.   I strongly recommend Dan O’Brien.

S. Worline – Geneva, IL
