Dennis O’Brien ’75 was appointed by Governor J.B. Pritzker to serve as an arbitrator on the Workers’ Compensation Commission of the State of Illinois. In his new role, Dennis conducts hearings and makes decisions about work-related injury disputes between employees and employers.



Before joining the commission, Dennis practiced workers’ compensation law for more than 35 years, most recently as vice president and secretary of Springfield law firm Livingston, Mueller, O’Brien and Davlin. Serving on the commission seemed like a natural next step.



“Over the years I’ve tried over a thousand cases before the commission, so I knew how the trials went and how to do them,” Dennis said. “The question was, do I have the demeanor to sit on the other side of the table? And the answer is that I do. I like to be respectful of people, and that’s what you need to be as an arbitrator. You have to show patience, and you have to be firm. It’s fulfilling work, and I truly enjoy it.”
