David Bonnar

A spokesman for the diocese and fellow priest noted how Bonnar "has shown himself to be a wonderful spiritual leader and a very competent administrator". Bonnar went into self-quarantine at the end of March 2020. This was a precautionary measure after one priest in the city tested positive for the COVID-19 virus, while another developed mild symptoms. In addition to his duties as a parish priest, Bonnar served as the editor of The Priest magazine, a position he took in 2014. He also worked as the chaplain of the Pittsburgh Steelers football team.

Pope Francis appointed Bonnar as bishop of the Diocese of Youngstown on November 17, 2020. He received his episcopal consecration from Archbishop Dennis Schnurr on January 12, 2021, at St. Columba Cathedral in Youngstown.

On July 23, 1988, he was ordained to the Catholic priesthood at the Church of Saint Gabriel of the Sorrowful Virgin in Whitehall, Pennsylvania, his home parish. Bonnar's first pastoral assignment was as parochial vicar of St. Vitus Parish in New Castle, Pennsylvania. He was then transferred to St. Rosalia Parish in Greenfield, Pennsylvania, four years later. He served as parish vicar of St. Thomas More Parish in Bethel Park, Pennsylvania, in 1996, before becoming director of vocations, rector of Saint Paul Seminary and director of the office for permanent deacons the following year. He was appointed as pastor at St. Bernard Parish in Mt. Lebanon, Pennsylvania, in 2009, serving there for 11 years. In July 2020, he was appointed the founding pastor of the newly formed St. Aidan Parish in Wexford, Pennsylvania.
