19six Architects

What 19six Architects does

19six Architects is a privately held, multidisciplinary design firm headquartered in Santa Barbara, California, with a statewide network of nine offices spanning the Central Coast, San Francisco Bay Area, Greater Sacramento, and Southern California. Founded in 1906 by A.B. Higginson and formerly known as PMSM Architecture, the firm has operated continuously for over 118 years as a project-based professional services practice providing architecture, structural engineering, interior design, and master planning. Services are delivered by a team of roughly 11 to 50 professionals, including Senior Principal Alan Kroeker and multiple Principals holding AIA and LEED AP credentials.

The firm serves seven principal verticals: K-12 education, higher education, healthcare, performing arts, civic, housing, and hospitality. Notable client engagements include OSHPD-certified medical clinics (Roberto S. Juarez Health Center, Northern California Fertility Medical Center), DSA-compliant schools (Natomas Charter School Resource Center, Heredia-Arriaga Dual Immersion School), community colleges (Riverside City College BLCIS, Cal Poly Crandall Gym renovation), affordable housing (Sonrisa Studio Apartments under Governor Newsom's EO N-06-19), civic facilities (City of Lincoln City Hall, Robert M. Falasco Justice Center, El Dorado County DOT Equipment Building), and hospitality (Red Hawk Resort + Casino Hotel). The portfolio demonstrates regulatory specialization in OSHPD and DSA-compliant California public construction, LEED-certified sustainable design, and historic preservation.

Revenue is generated through project-based professional service fees negotiated individually with public agencies, educational institutions, healthcare providers, and private developers. Pricing is quote-driven and tied to scope, complexity, and client sector (public vs. private), with engagements typically structured as multi-year contracts. Business development is sales-led: the firm pursues work through RFPs, RFQs, direct commissions, and design-build partnerships (e.g., AMG & Associates on the Cal Poly project), supported by a Marketing & Business Development Director, an awards-and-recognition program, community engagement, and content marketing via its website, news blog, and project videos. The firm is independently owned by its leadership team with no disclosed parent company, private equity backing, or institutional investors.
