Duane Morris added to its health law group this week, hiring a lawyer with longtime links to the industry.

Delphine O’Rourke joined Duane Morris’ Philadelphia office as a partner, fresh from a short stint in-house and after several years at a midsize health law boutique. O’Rourke was most recently vice president of legal services and associate general counsel for Ascension, which is the largest nonprofit health system in the United States, with more than 2,600 sites of care, including 151 hospitals.
