Won Sang Yoo
Won Sang Yoo founded Ranpac, Inc., in 1976. Won has successfully guided Ranpac through tremendous growth during the last four decades as it has become a dominant entity in Southern California land development. Under Won’s direction, Ranpac has been the instrumental consultant in some of the best-known development projects in Southern California, including Terramor, Bear Creek, Redhawk, Vail Ranch, Santa Rosa Springs, and Crowne Hill. Ranpac has developed or provided consulting services on more than 10 master-planned communities and 30,000 residential lots in various stages of development, and has recently added design, entitlement, and construction of self-storage facilities such as Smith Ranch Self Storage in Wildomar and Ranpac Self Storage Elm in Murrieta to its portfolio.
Also under Won’s direction, his engineering firm, Trans-Pacific Consultants, Inc. (TPC), successfully managed A.D. 159 and A.D. 161 to provide infrastructure for 11,500 acres of residential, commercial, and industrial development. Key components of this project were the widening of 8 miles of State highway from a 2-lane highway to a 6- to 10-lane highway. Won guided TPC from inception of planning feasibility studies and environmental analysis to design of construction drawings and construction management. Total construction cost was approximately $190,000,000.
Won holds a Master’s Degree in Urban Planning from California State University, Long Beach; and he is a Registered Professional Civil Engineer, a Registered Geotechnical Engineer, and a Licensed Real Estate Broker in California.
