MTA Welcomes New and Returning Board Members Confirmed by the State Senate

Updated June 3, 2022 6:30 p.m.

Metropolitan Transportation Authority (MTA) Chair and CEO Janno Lieber today welcomed six new members and three returning members to the MTA Board following the group’s confirmation by the New York State Senate.   

“I am excited to welcome this new group to the MTA Board at a time where the Authority is focused on using innovative strategies to bring riders back to mass transit and to secure new sources of revenue to address a looming multi-million dollar budget deficit,” Lieber said. “The six new and three returning members represent our diverse ridership, and I look forward to working with them to make using the MTA’s services more reliable, accessible and affordable for all customers.”    

The MTA is governed by a 21-member Board. Members are nominated by the Governor, with four recommended by New York City's mayor and one each by the county executives of Nassau, Suffolk, Westchester, Dutchess, Orange, Rockland, and Putnam counties (the members representing the latter four cast one collective vote). The Board also has six rotating non-voting seats held by representatives of organized labor and the Permanent Citizens Advisory Committee (PCAC), which serves as a voice for users of MTA transit and commuter facilities.
