about Us



Mammoth Holdings LLC was founded in 2002 by Gary Dennis and Chip Hackett. We are an Atlanta-based express conveyor car wash operator with brands in 11 states (Utah, Illinois, Indiana, Kentucky, Tennessee, Georgia, Louisiana, Mississippi, Alabama, South Carolina, and Florida). We operate more than 66 express conveyor car washes and four flex-service car washes under Busy Bee Car Wash, Finish Line Car Wash, Lulu's Car Wash, Marc-1 Car Wash, Ollie's Car Wash, Pals Car Wash, PitStop Carwash, PureMagic Carwash, Quick Wash Car Wash, Shine On Express, Swifty Car Wash, Ultra Car Wash, Wash Me Fast, and Wiggy Wash.

Mammoth is customer-focused operationally; operator-focused in its approach to acquisitions; and seeks to be the partner-of-choice for car wash operators who desire liquidity, growth capital, and a tax-deferred equity opportunity.

Mammoth is the first car wash acquisition platform formed by industry-insiders and is now the ninth-largest conveyor car wash operator in the United States according to Commercial Plus's Top 100 list.

In October 2018, Mammoth partnered with Red Dog Equity LLC, an Atlanta-based private equity firm, which, through its partnership with Tom Pritzker's family business interests, provided the equity for the Finish Line acquisition.
