About Wheeler Trigg O'Donnell LLP

Litigation boutique Wheeler Trigg O'Donnell is known for going to trial nationwide and winning on behalf of its Fortune 500 clientele. The high-profile clients who have received WTO's much sought-after litigation expertise come from a wide range of industries—such as manufacturing, telecommunications, energy, and services—and include Whirlpool, General Electric, Michelin, CenturyLink, USAA, FCA (formerly known as Chrysler Group), Ford, AT&T, Pfizer, Allstate, McKesson, Electrolux, Mercedes-Benz, and Vail Resorts, among others.

A Denver Firm

WTO was founded on February 1, 1998 by a group of five trial lawyers—including Mal Wheeler, Jack Trigg, and Mike O'Donnell—who left a full-service firm in Denver to build a nationwide practice dedicated to complex civil litigation. Still a relatively young firm, WTO has wasted no time making a name for itself. The firm was named a “Standout” in class action and products liability by BTI Consulting Group’s Litigation Outlook 2019, and in 2018, WTO was one of seven finalists for The American Lawyer’s National Boutique/Specialty Litigation Department of the Year Award. The firm and its attorneys have been recognized by the likes of U.S. News – Best Lawyers, Chambers USA, The Best Lawyers in America, and The National Law Journal.

L is for Litigation

WTO is known for its litigation chops, and for good reason. The firm’s attorneys have collectively taken more than 1,100 trials and arbitrations to verdict or award and 300 appeals to opinion. This litigation boutique specializes in civil trials and appeals in such areas as antitrust, class actions, complex commercial litigation, employment, intellectual property, investigations, mass torts, professional liability, and more.

Calling All Clerks

If you want to work at WTO, consider doing a clerkship first. Not only will you be among good company—83 percent of associates here completed state appellate court or federal judicial clerkships—but you'll also have some serious incentive. WTO offers one-time bonuses upon hire immediately following clerkships. An associate receives a bonus of $60,000 for a federal appellate court clerkship, $40,000 for a federal district court clerkship, $25,000 for a state supreme court clerkship, and $10,000 for a state appellate court clerkship.

WTO Foundation

WTO's volunteer efforts go beyond pro bono work. The firm founded the WTO Foundation, its own nonprofit charitable foundation, in September of 2005. Through the Foundation, the firm and its personnel have donated more than $1.8 million and volunteered thousands of hours to over 100 nonprofits. Eighty-five percent of firm members have participated in Foundation work benefitting organizations such as Legal Aid Foundation of Colorado, American Civil Liberties Union, Denver Kids, Inc., Denver Urban Debate League, and Denver Dumb Friends League.
