Sean O’Malley Managing Principal, Laguna Beach

“The city is the ultimate expression of man; we must understand what the land can tell us, so that we can ensure the survival of our natural systems and civilization itself.”

Sean O’Malley has over 30 years of experience in all aspects of the profession—including large-scale planning and construction. As an urban designer, planner, and landscape architect, he has implemented a unique approach to the design of cities, drawing upon the strength of site and utilizing natural structures as a framework for development. He is interested in what connects us—the places we have in common in our cities, streets, infrastructures, plazas and parks. He has created environments primarily in the U.S., Europe, and Asia.

Inspired By
