Judge Brook grew up in Raleigh, where he was raised by his single mother who taught in public schools. He attended Oberlin (formerly Daniels) Middle School and Broughton High School before receiving his undergraduate and law degrees from the UNC-CH.
Judge Brook first practiced law at a Raleigh firm and then worked as a staff attorney at the Southern Coalition for Social Justice in Durham. From 2012 to 2019, Judge Brook was the legal director of the American Civil Liberties Union of North Carolina.
Judge Brook has received numerous recognitions for his contributions to the legal profession in the state. He was inducted into the James E. and Carolyn B. Davis Society upon his graduation from Carolina Law and was subsequently honored as the school's Outstanding Recent Graduate. In 2016, the North Carolina Association of Women Attorneys awarded him with the Gwyneth B. Davis Public Service Award. Judge Brook was also the winner of the North Carolina Justice Center's Defender of Justice Litigation Award in 2017.
Since his April 2019 appointment to the North Carolina Court of Appeals by Governor Roy Cooper, Judge Brook has authored more than 75 opinions that speak to his rigor, fairness, and respect for each North Carolinian who appears before him.
Speaking about his work on the Court of Appeals, Judge Brook says, "I will never lose sight of the real human stakes before our Court. Every day I think about the people who have come forward asking that we hear their legal arguments. Whether it’s a criminal or civil matter, there is no more solemn responsibility than ensuring that those litigants get a fair hearing and receive our full, undivided, and deep attention to the details."
