Millie and Severson, General Contractors

What Millie and Severson, General Contractors does

Millie and Severson is a licensed California General Contractor (License #99031) founded in 1945 by USC engineering graduates Noble Millie and Charles Severson, headquartered in Los Alamitos, California. The firm provides preconstruction and construction services — including constructability reviews, BIM-enabled virtual design and construction, design-assist delivery, cost estimating, schedule monitoring, procurement, build-to-suit, core and shell, renovations, and tenant improvements — across ten sector specializations: Industrial, Healthcare + Life Sciences, Medical Office, Office, Cultural + Educational, Housing + Hospitality, Self Storage, Cold Storage, Interiors, and Parking. It serves enterprise and institutional clients including developers (Watson Land Company, Prologis, Bridge Industrial, Rexford Industrial, Duke Realty, Overton Moore Properties, Trammell Crow), REITs, healthcare systems (Cedars-Sinai, PIH Health, Good Samaritan, Stanford Medicine, UCSF), and universities (Biola, Pepperdine, Stanford Medicine), with offices in Los Alamitos, Pleasanton, Sacramento, Ontario (California), and Las Vegas (Nevada, opened 2025).

The firm's underlying technology platform combines BIM-driven 3D modeling, a real-time project management reporting system (as-bought analysis, budget recap, RFI log, submittal log), a dedicated in-house preconstruction team, and LEED certification expertise. It operates as an Employee Stock Ownership Plan (ESOP) company, with the ESOP established in 1974 now holding a controlling interest, alongside continued third-generation Severson family leadership (Ben Severson, President; Clark Severson, Chairman, General Counsel and CFO; Jonathan E. Severson, Chairman Emeritus). Revenue is generated through one-time, project-based construction contracts — priced via competitive bid or negotiated preconstruction estimating — with projects ranging from small tenant improvements to 1.3 million square foot industrial build-to-suits (Project Tire for Prologis, 2025).

The firm has completed over 4,000 projects since 1945, working on more than 50 hospital campuses and hundreds of industrial buildings, with tilt-up concrete construction as a legacy specialty dating to the 1950s industrial boom. Its go-to-market is sales-led and relationship-driven: a direct B2B engagement model through Division Presidents (Southern California, Northern California, Las Vegas), VPs of Preconstruction and Operations, and a Director of Project Development, with strong reliance on architect/consultant referrals (Boulder Associates 30+ years, RBB Architects 25+ years, Gensler) and repeat-developer pipelines. Marketing is conducted through earned media (ENR, BD+C, LABJ, San Francisco Business Times), NAIOP and AMFP industry events, an active LinkedIn presence, and a content-rich website, rather than paid digital channels.

Core offering

Millie and Severson is a licensed California General Contractor (License #99031) providing preconstruction and construction services across healthcare, industrial, medical office, commercial office, cultural/educational, housing/hospitality, self-storage, interiors, and parking sectors. Services span constructability reviews, estimating, BIM-enabled virtual design, scheduling, and procurement during preconstruction, followed by core and shell, build-to-suit, renovations, and tenant improvements during construction.

Product overview

Millie and Severson is a licensed California General Contractor (License #99031) that has delivered construction services since 1945 across two core service lines: Preconstruction and Construction. Rather than a unified SaaS-style product, its offering is a two-phase service platform with sector specializations serving as sub-portfolios. The Preconstruction service provides constructability reviews, estimating, schedule management, procurement, design-assist, and BIM-enabled virtual design and construction, which feeds directly into the Construction service for core and shell, build-to-suit, renovations, and tenant improvements. These two core services are applied across multiple sector specializations: Industrial, Healthcare + Life Sciences, Medical Office, Office, Cultural + Educational, Housing + Hospitality, Self Storage, Cold Storage, Interiors, and Parking, and they are supported by underlying technology capabilities such as BIM (Building Information Modeling), a real-time project management reporting system, and LEED/sustainability expertise. The company operates from offices in Los Alamitos (corporate), Pleasanton, Sacramento, Ontario, and Las Vegas, and is structured as an Employee Stock Ownership Plan (ESOP) company.
