Saul Ewing Arnstein & Lehr has named Jason St. John, former chair of the firm’s litigation department, as its new managing partner and CEO, firm leaders announced early Monday. He takes over for Barry Levin, who served in the dual titles since January 2014.

In a statement, firm leaders said St. John, who has practiced at the firm since 2005, will prioritize investing in the growth of the firm’s 16 offices and exploring new geographic markets as potential sites of expansion. St. John said the firm will continue to make investments in its talent management efforts and “transform its mentorship and training practices.”
