What P.W. Gillibrand does
P.W. Gillibrand Co., Inc. is a privately held, family-owned specialty aggregate products company founded in 1957 in Simi Valley, California. The company mines, processes, and distributes a diversified portfolio of sand and ground silica products across five operating sites in California (Simi Valley, San Juan Capistrano, Jurupa Valley/Riverside, Shafter/Bakersfield) and Texas (Brady), serving industrial, municipal, recreational, and equestrian customers throughout the Western United States, Canada, and Mexico.
The company's core technology centers on mining and physical processing of mineral deposits (including ancient marine sand deposits and a Brady, Texas industrial sand deposit), with capabilities spanning scrubbing, washing, air-drying, screening, and custom blending. Product lines include registered-trademark offerings such as Gillibrand Silver Sand, Gillibrand Industrial Sand, Riverside Milling specialty ground silica (200 and 325 mesh), and the NSF/ANSI 61 certified Raptor Filter Product Series (Sand, Hybrid engineered blends, and spherical glass Beads) targeting water filtration and well-drilling applications. Additional verticals include Equifina equestrian sand blends, volleyball and playground/recreational sands, golf and sports turf products, and a film location business at The Quarry at Gillibrand.
The business operates a sales-led B2B go-to-market with quote-based, transactional pricing (F.O.B. plant, Net 30 terms) conducted via dedicated phone lines, website quote requests, and a modest digital presence. Revenue derives from one-time product sales across six primary use-case segments: golf/sports turf, equestrian, municipal/schools, volleyball facilities, industrial filtration/well drilling, and film/entertainment. The company is currently led by Brandon Theising, grandson of founder Phillip Walton Gillibrand, following the 2022 passing of long-tenured CEO Celine Gillibrand, under whom the business expanded via three acquisitions.
