Our Firm
Building Better. Together.
Breen Design Group was founded in 1997 by Paul Breen with a focused mission: deliver exceptional Mechanical, Electrical, Plumbing, and Fire & Life Safety engineering to clients who demand precision, reliability, and results. Nearly three decades later, that mission has grown into something far greater.
Today, Breen Design Group is a full-service architectural and engineering firm serving clients across California and the nation. Our integrated team of licensed professionals brings expertise across six core disciplines: Architecture, Mechanical, Electrical, Plumbing, Civil, and Structural; providing clients with a single, accountable resource for even the most complex project demands.
A Team Built on Expertise
Our architects and engineers are licensed in California and multiple states, ensuring we can support projects wherever they take us. Many of our team members hold LEED AP accreditation, reflecting our commitment to sustainable, forward-thinking design. Breen Design Group is also a certified Small Business Enterprise through the State of California Department of General Services and a recognized Federal small business, credentials that position us as a qualified partner for both public-sector and private-sector work.
One Firm. Multiple Disciplines. Seamless Delivery.
What truly sets Breen Design Group apart is our ability to coordinate multiple architectural and engineering disciplines under one roof. Rather than managing separate consultants across different firms, our clients benefit from fully integrated in-house collaboration, streamlining communication, reducing delays, and producing high-quality construction documents that are clear, coordinated, and construction-ready.
Each discipline at Breen operates with its own depth of expertise while remaining closely connected to the broader team. The result is a cohesive, efficient process that simplifies project management for clients of all types and sizes.
Experience Across a Wide Range of Sectors
Breen Design Group has built a distinguished portfolio across a broad spectrum of project types, including Federal and government facilities, multi-family and affordable housing, mixed-use developments, healthcare, K–12 and higher education, retail, hospitality, high-rise, and net zero energy projects. Our clients include architects, developers, general contractors, public agencies, and private organizations, each with unique goals that our team is equipped to meet.
Your Strategic Partner for What's Next
At Breen Design Group, our size is our strength. We are large enough to handle projects of significant complexity and scale, yet nimble enough to provide the kind of personalized attention that larger firms simply cannot offer. We invest in understanding each client's vision, constraints, and goals and we deliver solutions that reflect that understanding at every stage of the project.
Whether you're breaking ground on a new development or navigating the challenges of a renovation, Breen Design Group brings the expertise, the credentials, and the collaborative spirit to get it done right.
