Mr. Clark began his career working for the State of Delaware’s Department of Finance, Division of Revenue as an economics analyst in the field of tax policy. During his tenure from 1989 to 1992, he authored several white papers analyzing Delaware revenue sources.

He entered Georgetown’s law school in 1992 where he earned honors as an articles editor of the Georgetown Law Journal, an Olin Law & Economics Fellow, and a member of the Order of the Coif. From 1995 to 1996, Mr. Clark clerked for Judge Boggs of the U.S. Court of Appeals of the Sixth Circuit. Mr. Clark then joined the law firm of Kirkland & Ellis as an associate from 1996-2001.

In 2005, Mr. Clark returned to Kirkland & Ellis LLP as a partner, where he litigated until his return to ENRD in 2018.
