Mr. Lyon received his Bachelor of Architecture degree from The Pennsylvania State University in 1967 and his license to practice architecture in California in 1974 (C-8537).    His experience encompasses all phases of architecture and construction management, successfully serving a wide range of clients including school districts, public agencies, health-care providers and private owners.


Jeff began his professional career as a Construction Manager, coordinating the work of architects and contractors on public school and U.S government projects throughout the country.  In the health-care field, he managed construction projects for the City of Hope Medical Center and other medical facilities in the Los Angeles area. 


Construction management projects at City of Hope led to numerous architectural commissions with that institution.  These included research buildings, patient care facilities, and development of a 20 year master plan which has since been largely implemented.


Medical work gave way to public schools in 1990, beginning with projects in Fallbrook, Murrieta, San Marcos and Temecula.  In 1996, he teamed with the Glendale-based firm of Leidenfrost/Horowitz, becoming a Principal Architect with the company and managing the firm’s work in San Diego and Riverside Counties.  Facilities included high schools, middle schools and elementary schools.


Throughout his long career, Jeff has maintained a keen enjoyment for private residential work, which is now his exclusive focus.  He has established close working relationships with the building and planning departments in Palos Verdes, Torrance and the surrounding beach cities, the primary geographical areas of his work.
