ACDelco – the true General Motors OE parts brand for Chevrolet, Buick, GMC and Cadillac – announced today that Mark Drennan is the brand’s new general director.

Before joining ACDelco, Drennan was director of GM Accessories, responsible for integrating sales and distribution with the design, production and marketing of GM’s vehicle accessories portfolio. Drennan previously served as a field zone sales manager and regional service manager.

“Mark’s track record of aftersales experience and leadership will be a valuable addition to an already strong ACDelco team,” said Eric Cunningham, executive director, sales and marketing, GM Customer Care and Aftersales. “Changes made in recent years have ACDelco on a strong trajectory and I look forward to working with Mark to continue that path of growth in the independent aftermarket.”

Drennan succeeds Robert Sanford, who will retire in early 2017 following a successful 35-year career with GM.
