What? You didn't know that the Mission Viejo Co. was once owned by an enormous tobacco company?
The Mission Viejo Co. was founded in 1963 by Donald Bren and the O'Neill family. Later, Bren sold his part of the company and bought the Irvine Co. instead. In 1969, Philip Morris invested in the Mission Viejo Co. and in 1972 they bought it outright. The company developed Mission Viejo, Aliso Viejo, and some communities in other states. The cancer people finally sold the company to developer J.F. Shea Co. in 1997.
