OUR MISSION
Omni Design's purpose is to create
better communities through design and collaboration.
We are an architecture and engineering firm rooted in San Luis Obispo, California. For over 40 years, we've partnered with public and private clients to deliver projects that strengthen the places where people live, learn and gather.
What makes us different is how we connect with our clients — through collaboration, responsiveness, and understanding. We translate their needs into creative solutions that deliver true value.
OUR VALUES
Three principles, one practice.
Our work is shaped by three core values that drive our decisions, and how we show up to work, treat our colleagues, partners and clients.
Integrity
Excellence
Collaboration

Centered Design
Our work is driven by a team of Architects, Engineers, Surveyors and designers that lives our values and serves with purpose— each with their own story, all pulling toward the same goal.
