Comcast Corp. has announced the appointment of Ray Roundtree to serve as the senior vice president of its Keystone Region, which covers much of the western half of Pennsylvania, the Ohio Valley and the Maryland panhandle. Roundtree, based in Pittsburgh, is now tasked with overseeing Comcast's financial, operational and strategic performance across this geographic region, which is also based out of Pittsburgh.

He succeeds Toni Murphy, who left the post in October for a promotion to serve as senior vice president of sales and marketing for Comcast's Central Division, which covers 11 Midwest and southeastern states. Roundtree first joined the Philadelphia-based company in 2000 as a director of business operations. He rose through the ranks of several financial management posts over the past two decades with the company, most recently ending up as the vice president of finance for Comcast's Baltimore-based Beltway Region.

Roundtree holds both an MBA and a bachelor's in finance from Penn State University.
