  • Laura (10/2015) (Avvo)
    "Gets Things in Motion."
         Patrick is very knowledgeable and knows how to get things going. I was stuck in a dead end personal collection case for years. He got the ball rolling and now it"s finally over. A lot of communication and no appearances in court were needed by me. Extremely happy now!
  • Terrance (06/2015) (Avvo)
    "Great Attorney."
         Mr. O'Brien was all the things you'd hope for in an attorney. He was responsive, extremely knowledgable and worked very hard to bring my case to a satisfactory conclusion. I felt like I was always in good hands. Good, caring and responsive attorney are hard to find so look no further.
  • John (07/2014) (Avvo)
    "Competent and Responsive."

    The City of Chicago Administrative Hearing went off without a hitch, establishing I was uninvolved on a question of a car I once (but did not currently) owned. Ben was on time, helped the prosecutor through the paperwork he'd ask I gather, and we were out in under 30 mins. Great work!
  • Dan (08/2014) (Avvo)
    DWS Case
         Mr. Lawson had me in and out of court for every appearance, and was able to get my fines lowered by half of what the state wanted to fine me. He was also able to get the state to drop the driver improvement school I would have had to do. I highly recommend for DUI or DWS cases.
