VALLEY FORGE, Pa. — AmerisourceBergen Corp. has promoted Robert Mauch to executive vice president and president of AmerisourceBergen Drug Corp., the division that distributes pharmaceuticals and offers pharmacy management services.

Mauch, 48, had been working as the company’s chief operating officer. He began his new duties on February 4, succeeding David Neu, who accepted the newly created role of executive vice president of retail strategy and president of Good Neighbor Pharmacy, a cooperative network of independently owned and operated pharmacies that has an affiliation with ­AmerisourceBergen.

“Bob has demonstrated tremendous leadership, and his powerful strategic thinking has played a significant role in enabling AmerisourceBergen to deliver on our promise to be a global health care solutions leader,” says Steve Collis, AmerisourceBergen’s president and chief executive officer. “In his new role Bob’s innovative, customer-centric vision will further our efforts to support pharmaceutical manufacturers and health care providers as they work to drive the best outcomes for patients.”

Mauch has been with AmerisourceBergen since 2007, when the company acquired Xcenda LLC, a health care consultancy founded by Mauch in 2002.

Neu has held positions at General Foods Corp., The L.A. Drug Co. and Bergen Brunswig Corp., which merged with AmeriSource Health Corp. in 2001.
