Simply the Most Awarded Commercial Trial Attorney in the State

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 more than 35 years, since graduating cum laude from Marquette University Law School in 1983.


Mr. Laing has been recognized by members of the bar and judiciary as one of Wisconsin’s top trial attorneys. Throughout his legal career, he has received numerous recognitions, including the following:

  • He was selected in 2012, 2016, 2017 and 2018 as one of the “Top 10 Lawyers” in Wisconsin by Super Lawyers/Milwaukee Magazine.

He’s streetwise and he’s bright and that’s tough to get both.”
  • He was selected as one of “Milwaukee’s Best Lawyers” by Milwaukee Magazine (Feb. 1995). The magazine stated that Mr. Laing is “very bright, hardworking and intense — no one will outwork him.”

The award is given annually to 10-20 Wisconsin attorneys and judges “whose efforts represent some of the best from our legal community.”
  • He is listed in three categories for inclusion in The Best Lawyers in America based on a “peer-review survey comprising more than 2.5 million confidential evaluations by the top attorneys in the country:” Commercial Litigation, Personal Injury Litigation–Plaintiffs, and Product Liability Litigation–Defendants.

  • He was described by Judge Kitty K. Brennan, then a trial court judge and now a judge with the Wisconsin Court of Appeals, as an attorney “of the highest standing in [his] profession” and his team as one of the “best sets of lawyers I’ve ever seen” in a Decision issued on April 15, 2005 in Southeast Wisconsin Professional Baseball Park District v. Mitsubishi Heavy Industries America, Inc., Case No. 02-CV-60.
  • He was described by the late Judge Rudolph T. Randa, then a judge with the United States District Court for the Eastern District of Wisconsin, as “an aggressive and indisputabl[y] qualified independent counsel” in a Decision issued on September 27, 2001 in Marshall & Ilsley Trust Co. v. Leslie, Case No. 97-C-427.

Among numerous 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.

In another high-profile case handled by Mr. Laing, he represented a bank being sued by Koss Corporation in connection with an embezzlement by one of Koss’s employees, Sujata Sachdeva, who obtained a portion of the embezzled funds from Koss’s accounts at the bank. Ms. Sachdeva embezzled $34 million from Koss, which is the ninth largest embezzlement in U.S. history. Koss sought $42 million in damages from the bank in the lawsuit. After more than five years of litigation, Koss’s case was dismissed by the trial court on summary judgment, which ruling was affirmed by the Wisconsin Court of Appeals on December 12, 2017.

$24.7 million (medical malpractice) (co-counsel)

$18.0 million (construction)

$5.6 million (legal malpractice)

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 41 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) from 1987 to 2016; been an invited speaker at 28 legal seminars/workshops; and been counsel in 67 published/reported decisions, some of which made new law.

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.
