  • Dean P. Laing is the President and Managing Shareholder of the law firm of O'Neil, Cannon, Hollman, DeJong & Laing S.C., a 40-attorney firm headquartered in Milwaukee, Wisconsin. He has been with the Firm for 33 years, since graduating cum laude from Marquette University Law School in 1983.

  • Mr. Laing's personality and trial skills have allowed him to be one of a select few attorneys who have been able to successfully practice both commercial litigation and personal injury litigation. In addition to representing Fortune 500 companies and other variously sized companies in their commercial litigation needs, Mr. Laing represents severely injured persons in prosecuting their personal injury claims. His passion for those cases is partially derived from his having two brothers with cerebral palsy. As a result of growing up in that environment, Mr. Laing understands what families go through in caring for loved ones with special needs, and is able to communicate that to insurance companies, defense counsel, judges, and juries.

Additional Information

  • Mr. Laing is board certified in Civil Trial Advocacy and Civil Pretrial Practice Advocacy by the National Board of Trial Advocacy, and is a frequent author and speaker on legal issues involving evidence, torts, insurance and trial tactics.

  • He has authored 40 journal articles and book chapters, including the Evidence Chapter of the Wisconsin State Bar's annual book entitled Annual Survey of Wisconsin Law each year (but two) since 1987; been an invited speaker at 27 legal seminars/workshops; and been counsel in 53 published/reported decisions, some of which made new law.

Case History

  • Among numerous other high-profile cases in which he has been involved, Mr. Laing was the lead trial attorney for Mitsubishi Heavy Industries America, Inc. in a lawsuit relating to the construction of the retractable roof of Miller Park (the home of the Milwaukee Brewers), which Judge Kitty K. Brennan called "the biggest case [Milwaukee] County has ever seen." The case, filed by the Southeast Wisconsin Professional Baseball Park District, sought $50 million in damages from Mitsubishi for alleged defects in the retractable roof constructed by Mitsubishi. Mitsubishi denied liability and filed a counterclaim seeking additional costs incurred in constructing the roof due to material changes made to the roof's design after Mitsubishi bid the job. The case involved claims of $140 million, and generated the taking of 162 depositions in three countries, the production of 2.9 million pages of documents, the filing of 96 substantive motions, and several trips to the appellate court. After three days of mediation involving 22 attorneys from seven states, a settlement was reached one week before the scheduled trial, resulting in Mitsubishi paying nothing on the Baseball Park District's claims and receiving $18 million on its counterclaim.
