  • “Judge Conen works tirelessly to resolve cases at mediation. He is well prepared and understands the central issues in question. Unlike many mediators, Judge Conen will continue to work with the parties even if mediation failed to see if a resolution can be reached prior to trial.”

  • “My firm and opposing counsel engaged Jeffrey Conen/Hansen Reynolds to facilitate and conduct a binding mediation through the Chicago Bar Association mediation service in an exceptionally difficult and emotionally charged matter. Mr. Conen was excellent in his handling of the file from intake through conduct of the mediation and we ended up resolving the matter through his efforts in far shorter than was ever expected. I highly recommend Mr. Conen and look forward to using his services again should the need ever arises in the future.”

  • “Tim Hansen is incredibly effective in a courtroom. Maintaining a low key good humored demeanor he suddenly thrusts to the heart of an issue in a way that sticks in the mind. It was a pleasure to watch him take a case with many difficulties and resolve it favorably for his client while leaving everyone in the case his friend.”
