Postmaster General Megan J. Brennan announced the selection in a memo to postal officers on April 21.
In the announcement, Brennan noted Penner's 31-year postal career, saying it has given Penner a "well-rounded experience with our stamp program from perspectives throughout the organization."
She pointed out that since 1998 Penner has worked at Postal Service headquarters in marketing, operations, business service network and sales.
