Mammoth Holdings
Mammoth Holdings, the DiSano family's Atlanta-based platform, has consolidated over 130 express car washes since 2015.
Mammoth Holdings
Mammoth Holdings was formed by the DiSano family in 2015 with a concentrated bet on express car wash real estate — a niche where automated, subscription-based operations combine high-margin recurring revenue with underlying property ownership. The firm operates under the premise that a fragmented market of single-location operators could be consolidated into a regional platform with centralized branding, technology, and procurement. The investment strategy focuses almost exclusively on acquiring and developing express conveyor car washes, with a secondary focus on related real estate and consumer automotive services. The portfolio spans more than 130 sites under several operating brands, including Coastal Carwash, Shine-N-Go, and Marc-1, across states such as Georgia, Florida, Texas, and Illinois. Rather than acting solely as a financial sponsor, Mammoth holds operating control over its sites, integrating membership programs and subscription models — a structure that generates predictable cash flows while building an asset-backed portfolio. While total deployment is undisclosed, the scale of 130-plus locations suggests significant capital concentration in industrial-service real estate. The firm is led by President and CIO Gary T. DiSano, alongside Chairman Dean DiSano, with the platform's growth accelerated by strategic partnerships, including a 2020 investment from Red Dog Equity and Eagle Merchant Partners. The firm has not disclosed adjacent philanthropic vehicles or third-party capital programs, operating as a private investment company focused on its core roll-up strategy. The structural differentiator is Mammoth's blend of a family-office holding company with a private-equity-style consolidation playbook — a model rarely executed with this degree of operational integration. Rather than a diversified multi-asset allocation, the DiSano family has opted for deep vertical concentration in a single, cash-generating service sector, creating a proprietary operating platform that blurs the line between family office and permanent-hold operating company.

Frequently asked questions
Is Mammoth Holdings structured as a family office or a private equity firm?
Mammoth operates as the DiSano family's private investment platform, structured as a holding company rather than a fund with outside limited partners. While its roll-up consolidation strategy resembles private equity, the firm invests permanent family capital and maintains direct operational control over its portfolio, without the typical fund-life constraints or return-of-capital mandates of a PE fund.
How does Mammoth source and execute its express car wash acquisitions?
Mammoth targets fragmented single-location express car washes across the Sun Belt and Midwest, acquiring assets through a centralized M&A function. The firm evaluates sites based on traffic patterns, real estate fundamentals, and membership-program conversion potential, integrating acquired operations under regional brand umbrellas while standardizing technology, pricing, and subscription models.
What investment stages or asset classes does Mammoth target beyond car washes?
Mammoth's disclosed deployment is concentrated entirely in express-car-wash operating real estate and related consumer automotive services. The firm has not publicly announced material activity in venture, private credit, or traditional multi-asset allocation strategies, making it one of the more sector-concentrated family-backed investment platforms known.
Who runs the investment and operational decisions at Mammoth?
Gary T. DiSano serves as President and Chief Investment Officer, leading acquisition strategy and day-to-day operational oversight. Co-Founder Dean DiSano acts as Chairman, providing governance and strategic direction for the family's platform, which has expanded to more than 130 locations since 2015.
Does Mammoth maintain philanthropic structures or separate family-office functions?
Mammoth has not publicly disclosed a separate philanthropic foundation or distinct family-office services entity. The platform appears to function primarily as an operating holding company for the car wash portfolio, with no public information on wealth-planning or trust-company operations beyond the investment vehicle.
How is Mammoth related to Eagle Merchant Partners and Red Dog Equity?
Eagle Merchant Partners and Red Dog Equity made a growth investment in Mammoth Holdings in 2020 (per public record), providing expansion capital alongside the DiSano family. The partnership underscores Mammoth's hybrid structure — a family-backed platform that selectively brings in institutional co-investors to scale a concentrated operating strategy without converting to a traditional fund model.
What is Mammoth's geographic footprint?
Mammoth's portfolio concentrates on the Sun Belt and Midwest, with confirmed positions in Georgia, Florida, Texas, and Illinois. The firm selects locations based on favorable weather patterns for year-round demand, population growth, and fragmented local ownership — criteria that have driven site density in Southeastern and South Central markets.
