Cathleen M. Devlin is a Litigation Partner at Saul Ewing Arnstein & Lehr LLP, in the Firm’s Philadelphia and Chesterbrook, PA offices.  She serves as a Vice-Chair of the Firm’s Litigation Department, a Co-Chair of the Firm’s Environmental Industry Group, and as a member of the Firm’s Executive Committee.


Cathleen is a seasoned trial lawyer and negotiator, with over 25 years of experience handling complex commercial contract and business tort matters, defense of class actions, and environmental disputes. On the environmental front, Cathleen has litigated and tried environmental cases for corporate clients identified as potentially responsible parties (PRPs) at former industrial facilities, smelter sites and landfill sites nationwide. Her work on these matters involves coordination with experts and federal and state environmental agencies, as well as active participation on PRP committees at various stages of threatened and pending enforcement and cost recovery actions. Her experience also includes litigating corporate successor liability and alter ego liability issues, contractual indemnification claims and equitable allocation of cleanup costs. Cathleen also counsels clients in navigating investigations and audits arising from federal and state government inquiries outside the environmental context. Favorable outcomes that she has achieved for her clients have come by way of successful motions, trial judgments, appeals, arbitration awards and negotiated settlements.


Cathleen is an avid golfer, and enjoys counseling golf industry clients and golf club pros on golf course safety risks and neighboring property owner disputes. Cathleen is also passionate about supporting mixed-breed dog rescue and adoption organizations. She is committed to serving the legal profession through active participation in the leadership of the ABA Litigation Section and as a member of the International Association of Defense Counsel.
