Pro-Vac
Pro-Vac was established in Puyallup, Washington, as an industrial services company before evolving into the operating anchor for its founder’s family capital. While the exact founding year is not publicly pinned, the entity has built out a regionally dense fleet that now covers the Pacific Northwest, Mountain West, and select Southwest markets. The operating company provides subsurface utility engineering, stormwater management, and critical infrastructure maintenance, making the family’s wealth deeply tied to the performance of physical, hard-to-replicate asset networks. The strategy centers on organic fleet expansion and bolt-on acquisitions within the hydro-excavation and environmental-maintenance corridor. Confirmed equipment holdings include a large inventory of Vactor, GapVax, and Camel vacuum trucks deployed across municipal sewer, industrial plant, and energy-utility contracts. The firm markets a fleet value exceeding $250 million, a figure that functions as a proxy for tangible book equity in the absence of disclosed AUM. Geographic reach extends from Washington and Oregon into Idaho, Colorado, Arizona, and Texas, with satellite yards serving metro utility districts. Leadership sits with CEO Graham Riddell, who has guided the family-backed enterprise through a period of private-equity-style consolidation within the infrastructure-services sector. Adjacent structures include the operating entity itself, which functions as the primary investment vehicle. June 2023: Pro-Vac acquired the assets of Texas-based Dart Vacuum Services, extending its hydro-excavation footprint into the Permian Basin and Gulf Coast energy markets. The deal underscored a posture of financing growth through operating cash flow and senior bank lines rather than outside capital. Pro-Vac’s structural differentiator is that the family office is not a separate allocator alongside a business — it is the business. There is no fund structure, no outside limited partners, and no publicly reported allocation to third-party managers. The industrial fleet is the portfolio. This architecture creates an unusually illiquid, cash-flow-driven wealth engine that is valued by what the machines earn on five-year utility contracts, not by quarterly marks.

Frequently asked questions
Who runs Pro-Vac’s investment decisions?
Graham Riddell, as CEO, directs capital allocation. Because Pro-Vac is an operating business rather than a separate investment entity, strategic decisions center on fleet procurement, geographic expansion, and M&A within the industrial-services niche. The single-family-office function is embedded in the corporate treasury rather than run through an independent investment committee.
Is Pro-Vac a family office or an industrial operator?
It is both — the operating company doubles as the primary investment vehicle for the family's wealth. Unlike a traditional family office that diversifies across asset classes, Pro-Vac concentrates nearly all its capital in vacuum-excavation equipment, real estate for satellite yards, and adjacent service lines. No separate asset-management entity is publicly referenced.
What is Pro-Vac’s known posture on co-investments alongside external GPs?
The firm does not appear to participate in GP-led fund commitments or open-market co-investments. Its capital deployment model relies on internal financing of equipment purchases and infrequent tuck-in acquisitions, all completed without disclosed institutional equity partners. The balance sheet is funded by operating cash flow and bank credit.
How large is Pro-Vac’s asset base?
Total AUM is not publicly disclosed. The company has stated that its fleet alone is valued above $250 million, a number that serves as a rough floor for its tangible asset base. This figure does not include owned real estate, working capital, or goodwill from acquisitions, so the enterprise value is presumably higher.
Which sectors does Pro-Vac explicitly avoid?
The firm is entirely focused on critical infrastructure maintenance — subsurface utility engineering, hydro-excavation, stormwater management, and pipeline inspection. It does not operate in financial services, technology venture, real estate development, or consumer goods. The family’s wealth is deliberately concentrated in the industrial-services sector where the operating management has decades of domain expertise.
Where does Pro-Vac’s underlying wealth come from?
The wealth originated from building and operating one of the largest vacuum-excavation fleets in the western United States. The founder family retains full ownership, and no liquidity event or outside capital raise has been publicly reported. The fortune is a product of multi-decade organic growth serving municipal utilities, energy companies, and industrial plants.
Does Pro-Vac maintain philanthropic structures?
No foundation or donor-advised fund is publicly tied to Pro-Vac or the Riddell family. The firm’s external communications focus exclusively on commercial operations, and no charitable entity appears in public record filings linked to the office. Any personal giving is handled privately by the principals.
