Serling Rooks Hunter McKoy Worob & Averill LLP, the New York-headquartered music and entertainment law firm, has rebranded as McKoy Worob Averill Scott & Koenig LLP.
The change, which took effect in January 2026, follows the departure of named partners Reid Hunter and Joe Serling.
Following the transition, longtime partner Jeffrey Koenig has been elevated to named partner, while Margo Scott, joins as a new named partner.
Three additional partners also join the firm: Atticus George Carroll, who arrives from Warner Records, where she was Vice President of Business & Legal Affairs; plus Anamaria Laguna-Dunn and Kate Glinert, who have both been elevated from Senior Counsel.
The firm’s pre-existing leadership of Mike McKoy, Jeffrey Worob and Craig Averill remains in place.
