Judge Robert W. Clark was born in Meriden in 1971 and was raised in Wallingford, where he attended public schools before entering college. After graduating from the University of Connecticut, cum laude, in 1993 with a Bachelor of Arts degree in English, he earned a Juris Doctor degree, with high honors, from the University of Connecticut School of Law in 1997, where he served as Executive Editor of the Connecticut Law Review.

In February of 2021, Governor Ned Lamont nominated Judge Clark to be a judge of the Connecticut Appellate Court. He was confirmed by the Connecticut General Assembly in March of that year and was sworn into office on March 23, 2021. Judge Clark previously served as a Superior Court judge in the Bridgeport GA and juvenile court.

Immediately prior to his appointment to the Appellate Court, Judge Clark served as General Counsel to the Office of the Governor for the State of Connecticut from 2019 to 2021. In that role, he served as chief legal advisor to the Governor, providing legal counsel to the Governor, his senior staff, and commissioners on a broad range of state and federal legal issues, including the Executive Branch's interactions with its co-equal branches of state government and the federal government.

From 2004-2018, Judge Clark worked in the Connecticut Attorney General's Office, first as an Assistant Attorney General in the Special Litigation Department and later as Special Counsel to Attorney General George Jepsen. Prior to joining the Office of the Attorney General, Judge Clark worked for the law firms of Day, Berry & Howard LLP (now Day Pitney) and Kramer Levin, handling commercial litigation and bankruptcy matters in state and federal courts.

Judge Clark and his family reside in Durham, Connecticut.
