DeLeon began his career in 1959 playing keyboard with the Kent Whitt and the Downbeats band, all fellow students at Modesto high school. The band a stopped performing in 1963, but not until they had performed in a USO tour for troops in Alaska and Asia. The band spent 3 1/2 months touring Vietnam, Taiwan, Korea, Japan, and the Philippines before the breakup started with DeLeon and other members of the band being drafted into military service.
DeLeon fondly remembers the fifties and sixties and enjoying cruising up and down 10th and 11th streets in downtown Modesto with his friends. After finishing his military commitment, DeLeon became interested in the broadcasting business and after obtaining a broadcast/operator license in Los Angeles, he returned to Modesto in 1963 and started working at KLOC radio station in Ceres, which had just been put on the air by country musician and media mogul Chester Smith. A few months later, he landed a position at KFIV as an on-the-air personality staying until 1972.
DeLeon moved on to KTRB in the 80's before eventually making his way into the real estate business working his way up to Vice President of sales and training for Century 21 M&M and Associates Realty in Modesto.
In 2004 DeLeon, and several other veteran radio personalities in the Modesto area, formed the Modesto Radio Museum group dedicated to preserving the history of local radio broadcasting. At 69, DeLeon lives in Modesto with his wife of 46 years Ronie. They have one daughter and one grandson.
