SRM Concrete is the largest family-owned ready-mix concrete manufacturer in the United States, founded in 1999 by Mike and Melissa Hollingshead from a single backyard plant with three trucks. Today the company operates 563 concrete plants across 24 states and employs more than 8,500 people, with CEO Jeff Hollingshead leading the business.
Beyond ready-mix concrete, SRM operates a network of related businesses: SRM Materials runs 33 quarries supplying aggregates, while Hollingshead Cement manages 12 cement terminals and Hollingshead Harbor oversees associated port facilities. This vertical integration gives the company control across the construction materials supply chain, from raw materials to finished concrete delivery.
SRM's growth has been driven by more than 100 strategic acquisitions since 2012, expanding its footprint steadily while remaining privately held and family-run. The company serves customers ranging from residential builders to large-scale commercial developers. Its five stated cultural principles are safety, quality, kindness, cleanliness, and a go-getter mentality - values the company describes as core to how it operates across all locations.
