David Hoffmann has been appointed Chairman and CEO of Mammoth Holding, LLC, an Atlanta-based conveyor car wash operator with a portfolio of brands in 10 states. Hoffmann served as CEO of Dunkin' Brands from July 2018 until its $11 billion sale to Inspire Brands in December 2020. Prior to Dunkin' Brands – where he also served as president beginning in 2016 – Hoffmann spent twenty-two years at McDonalds, most recently as President of High Growth Markets and previously President of Asia Pacific, Middle East & Africa Markets.

This is one of the most exciting days in Mammoth's history, said Gary Dennis, Mammoth's co-founder who served as chairman and chief executive officer of Mammoth prior to Hoffmann's appointment. Dave is an extraordinary executive and is the right person to take Mammoth to a new level of operational excellence and scale. He has a keen appreciation for Mammoth's unique operator-focus, and we know he will do great things at Mammoth like he did at Dunkin' and McDonalds. Dennis will assume the new role of vice chairman going-forward and will focus on acquisitions and special projects.

I'm honored to be assuming the role of chairman and CEO from Gary Dennis, who has done a remarkable job, said Hoffmann. I'm excited to build on Mammoth's successful operator-focused strategy and see many opportunities to leverage the experience I've had working with franchisees and owner-operators to elevate service and build consumer loyalty.

The car wash model is prime for disruption, said Hoffmann. The Mammoth team has built a foundation from which we will launch an industry-leading customer service model to spur growth and deliver outstanding value for our operators

Dave Hoffmann is a talented leader, team-builder and entrepreneur who brings real passion to this role, said Marcus Kittrell, Mammoth's executive vice president and a board member. The other owner-operators and I have been impressed with Dave since he joined Mammoth's board in August, and we expect to see great benefits from his deep expertise implementing operational excellence and digital transformation.

Hoffmann joined Mammoth's board of directors in August 2021 and made a significant personal investment in the company.
