At an annual reorganization meeting, the Township Committee selects one of its members to serve as Mayor and another as Deputy Mayor.

Randolph (R, term on committee ends 2022; term as deputy mayor ends 2020), Steve Keefe (R, 2021) and Jose Medeiros (R, 2020) and Paul J. Muir (R, 2020).

At a special meeting in July 2015, The Township Committee selected Jose Medeiros to fill the seat expiring in December 2017 that was vacated earlier that month following the resignation of John Graefe, who was moving out of the township.

Bethlehem Township's municipal buildings are located on Mine Road.
