Wheeler Trigg O'Donnell LLP

The 90+ trial-tested lawyers of the Denver civil litigation firm Wheeler Trigg O'Donnell ("WTO") are known for trying precedent-setting cases in difficult jurisdictions throughout the country. WTO has tried more cases to verdict than any similar-sized firm in the region – 45 trials and 41 arbitrations in the last five years.

WTO handles trials, appeals, arbitrations, and related areas of complex civil litigation, including class actions and multidistrict litigation, on a local, regional, and national basis. We serve as resolution and trial counsel for many of the nation's best-known companies, including Whirlpool, General Electric, Chrysler Group, Pfizer, McKesson, Mercedes-Benz, Advanced Bionics, Allstate, Ford, and USAA.

WTO has defended clients against allegations related to bad faith, breach of contract, breach of warranty, product liability, professional liability and malpractice, franchise and distribution matters, intellectual property infringement, personal injury, toxic torts, discrimination and employment management, and other legal issues related to business operations. We represent companies and individuals in such diverse industries as pharmaceuticals, medical devices, insurance, automotive, banking and financial services, construction and engineering, energy, consumer products and services, health care, law, accounting, natural resources, telecommunications, food service, asbestos, manufacturing, and franchise and distribution.

Our lawyers are admitted to practice law in 19 states and the District of Columbia. We have served as lead trial counsel in all 50 states and have tried cases to verdict in 45 states, Puerto Rico, the Virgin Islands, and the District of Columbia. We have appeared before the U.S. Supreme Court, most of the U.S. courts of appeals, two-thirds of the U.S. district courts, over a dozen state supreme courts, and several federal regulatory agencies.

WTO has been able to attract first-rate lawyers to complement the depth and experience of our original team because of our reputation for excellence, the quality of our clients, and the challenge of their legal problems. Six of our partners are elected Fellows of the American College of Trial Lawyers and firm chairman Mike O’Donnell is an ACTL Regent. Martindale-Hubbell has given the AV peer-review rating to over 60% of our partners. Over 70% of our associates have served a state or federal trial or appellate judicial clerkship. Our firm and lawyers consistently appear in local and national rankings surveys such as Best Lawyers, Chambers USA, The Legal 500 U.S., and Colorado Super Lawyers.

Beyond the courtroom, WTO's 200 employees make up the professional and collegial culture that has earned us a top-10 ranking for the past nine years in the annual Denver Business Journal's best places to work survey. WTO was number one in 2008, 2010, and 2012. Our community-mindedness is unmatched as evidenced by our selection to receive the Denver Business Journal's 2010 Partners in Philanthropy award for the volunteer hours and charitable contributions donated to the community through the WTO Foundation.
