What RBB Architects Inc does

RBB Architects Inc is a privately held, California-domiciled architecture firm founded in 1952 as Rochlin & Baran and headquartered in Los Angeles, with a secondary office in Lafayette. The firm specializes exclusively in the programming, planning, and design of complex institutional facilities — with 100% of staff expertise dedicated to healthcare architecture, alongside smaller liturgical and campus master-planning practices. It serves enterprise healthcare customers including Cedars-Sinai, UCLA Health, Dignity Health, Providence St. Joseph, Hoag, PIH Health, and Los Angeles County, and has completed more than 15,000 projects representing over $500 million in designed construction value annually.

The firm's technical platform centers on Building Information Modeling (BIM), Integrated Project Delivery, Design-Build methods, and Lean Planning / simulations used to optimize throughput, room turnaround, and operational efficiency. It holds LEED AP staff certifications and is recognized as a green-building design firm (ENR #86), with deep expertise in California OSHPD regulatory approvals and seismic compliance — both of which function as regulatory moats. Project work spans acute care hospitals, children's hospitals, cancer centers, ambulatory surgery centers, and 76-acre campus master plans, delivered by long-tenured principals and project teams (some clients have retained the same team for 15+ years).

RBB generates revenue through professional architectural services on a project-based, custom-engagement model, secured via direct enterprise sales, RFP responses, and preferred-provider relationships. Its go-to-market relies on long-cycle healthcare construction projects, repeat clientele (90% of business), and reputation-driven award positioning (HCAI #1, LA Business Journal #28, NY Architectural Design Silver Award 2024). The firm is MBE-certified with the City of Los Angeles and CBE-certified with Los Angeles County, unlocking public-sector healthcare procurement. No parent company, private equity, or venture capital ownership is indicated.
