[1][2][3] Considered one of the pioneers of Radyo Patrol, which counts as contemporaries, among others, Rey Langit, Noli de Castro, Joe Taruc, Mario Garcia, Bobby Guanzon, Orly Mercado and Bong Lapira, Baron, started his radio career with the general information program Gintong Kaalaman on the old DZAQ, the forerunner of DZMM and later DWPM.

During the Martial Law era, he also worked as one of the news anchors of the station DZSA 1230 kHz (now DWXI 1314 AM).

When ABS-CBN returned on the air after the Marcos regime, he hosted the radio program Knowledge Power as well as its television spin-off.
