Thomas Leonard, Lawyer and Member at Cozen O’Connor, has been recognized as a Marquis Emerging Leader for their contributions and achievements in the field of business litigation.

Growing up in a family with many lawyers gave Mr. Leonard the unique perspective to see the value of their work. He followed in his family’s footsteps, including his two older sisters and made the decision to pursue the practice through his academic pursuits. It was clear to him when he joined the mock team in college that this was the right track for him. After earning a Bachelor of Arts in political science at Boston University, cum laude, in 2010, Mr. Leonard earned a JD from Villanova University, cum laude, in 2013. He was admitted to practice through the New Jersey and Pennsylvania State Bars in 2013.

Mr. Leonard commenced his career in law as an intern for the Honorable Berle Schiller for the U.S. District Court for the Eastern District of Pennsylvania in 2011. Since 2013, he has been an attorney with Cozen O’Connor, and became a member of the firm’s business litigation practice group in 2019. In addition to these roles, he garnered experience as a co-president of the Boston University Mock Trial Organization, as well as with the Villanova Law Review. Mr. Leonard attributes his success to hard work and a great support system from his family and friends. He also cites great training and preparation within the firm as aids to the success of his career.

Mr. Leonard considers the highlight of his career thus far to be obtaining membership at Cozen O’Connor after only six and a half years out of law school. Getting through his associate time and into membership in six and a half years was probably his biggest accomplishment. Mr. Leonard’s motto is, “Do well with whatever it is you do.” In five years, Mr. Leonard hopes to be still at the firm and trying to build his career and become more and more valuable to the firm, through client development and through continued expertise as a good lawyer.
