Aaron O’Dell is an experienced trial lawyer in Winston’s Dallas and Los Angeles offices that has been described by clients and opposing counsel as “no-nonsense” and a “tenacious tactician.”

Aaron has extensive experience in all aspects of major case litigation and trial work, including trying business and commercial, products liability, mass tort, and employment cases to verdict in both jury and bench trials. Aaron’s litigation experience is also broad, having successfully litigated the aforementioned complex commercial cases, as well as securities and white collar matters to favorable judgments or settlements. 

Aaron has served as trial counsel, on trial teams, and on company defense leadership teams for many high-profile clients and matters. Recently, Aaron was on the trial team that successfully defended a leading healthcare company in an important products liability trial related to premature infant formula, which was reported by major media outlets, including The Wall Street Journal and Bloomberg. Aaron has also been recognized for several years as one of the Best Lawyers in America®. 

With Aaron’s trial experience, he prepares each aspect of a case – from document discovery, to depositions, to motion practice – with trial in mind, which allows Aaron to litigate cases efficiently to save clients from unnecessary and costly litigation and puts his clients in the best position to either try the case to victory or settle favorably. 

Aaron is also extremely adept at counseling general counsel and company executives facing litigation and preparing executives, employees, and experts for deposition and trial testimony.        

Aaron has a distinct love for and commitment to trial work and teaching the next generation of lawyers, as Aaron is fortunate to be a visiting professor at the University of Notre Dame Law School, teaching Trial Advocacy, and a member of the faculty of Winston’s Institute of Trial Advocacy and Winston University. 

Finally, Aaron is an admirer and a big believer in Theodore Roosevelt’s “Man in the Arena” philosophy and incorporates it into his practice and trial teams: 

“It is not the critic who counts; not the man who points out how the strong man stumbles, or where the doer of deeds could have done them better. The credit belongs to the man who is actually in the arena, whose face is marred by dust and sweat and blood; who strives valiantly; who errs, who comes short again and again, because there is no effort without error and shortcoming; but who does actually strive to do the deeds; who knows the great enthusiasms, the great devotions; who spends himself in a worthy cause; who at the best knows in the end the triumph of high achievement, and who at the worst, if he fails, at least fails while daring greatly, so that his place shall never be with those cold and timid souls who neither know victory nor defeat.”

- Theodore Roosevelt, “Citizenship in a Republic,” Paris, April 23, 1910.
