Pangilinan began his career in Houston, Texas back in 1987,[3] working for a rhythmic top 40 station KNRJ (now KHMX 96.5) under a different DJ name, Rippin' Rich. However, his break into the radio world was when in 1993, joined KRBE 104.1 FM under Tom Poleman and Paul "Cubby" Bryant and became DJ Rich. From there he held radio mixshows with KHFI-Austin and KTFM-San Antonio. In 1995, he left Texas for New York City to work for WHTZ-Z100 and Tommy Boy Records.

While at Tommy Boy Records, Pangilinan was credited for his work on the platinum-selling "Jock Jam Megamix" and Jock Jams compilations. The "Jock Jam Megamix" was one of the first legalized mash-ups to sell over 500,000 copies according to SoundScan in the late 1990s.
