David W. Sunday Jr. was sworn in as the District Attorney for York County, Pennsylvania in 2018. Before he was District Attorney, Sunday was previously in the United States Navy.
In 2013, Sunday worked with Coroner Pam Gay to establish the York County Heroin Task Force, now the York Opioid Collaborative. It was this time spent in the community, that Sunday realized the impact he could have when seeking to maximize public/private partnerships. Sunday now serves on the Board of Directors for the York Opioid Collaborative, the Criminal Justice Advisory Board, York County Prison Board and Better York Board.
