Driven Distribution Group has appointed Bill Westerman as CEO, formalizing a leadership transition that began in February when he stepped into the acting CEO role. The automotive aftermarket warehouse distributor is backed by Oridian Capital Partners, the Washington, D.C.-based private equity firm formerly known as HCI Equity Partners.

Launched in late 2024 by Oridian/HCI, Arlington, TX-based Driven Distribution Group distributes automotive aftermarket hard parts, consumables and accessories through brands that include Tri-State Enterprises, Eagle Auto Parts and Chicago Parts & Sound and Battery Service Corp. (acquired in January 2026).

Westerman brings more than 30 years of leadership experience across the automotive, manufacturing and transportation sectors. His background includes executive roles at Volvo Trucks North America and Tenneco Automotive, followed by a 20-year tenure at Genuine Parts Co., where he served as a division president before becoming chief operating officer of NAPA Auto Parts. Most recently, he was CEO and board member of Road Tested Parts.

He also served as an independent board member for Driven Distribution Group over the past year, helping guide the company during a period of expansion. The company has completed several acquisitions since its launch in 2024, including Chicago Parts & Sound and Quality Parts Warehouse.

“We are truly excited to have someone with the experience and capabilities that Bill brings to the DDG organization,” said Scott Gibaratz, partner at Oridian Capital Partners, in a company announcement. He added that Westerman had already made a positive impact during the transition period.

Driven Distribution Group was also recently named to Inc.’s 2025 and 2026 regional lists of fastest-growing private companies in the Southeast.
