Sean O’Malley Managing Principal, Laguna Beach

“The city is our imprint upon this planet. How we plan and develop them will determine our collective survival.”

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.
