DJ Prostyle was born Alexander Ricardo Santelises, in Queens, New York. When he was 13 years old he moved to Orlando, Florida, and at his sister's sweetsixteen party, Santelises says that he was drawn to the attention that was being given to the dj, and it was that night that he was insired to become a dj himself.
In high school and 16 years old, he got a chance to be on a college radio station and began mixing at local parties and releasing mixtapes (cassettes, not CDs) on an almost weekly basis to push his craft around town.
His dedication eventually landed him a spot with the biggest radio station at the time in Orlando, 102 Jamz, where he would soon have the top show on the station.
Several years later, at a BET Spring Bling, he would meet DJ Enuff, who invited Prostyle to join his Heavy Hitters team. From there, he went on to become a rotating DJ on the BET music video show Rap City, and from 2005 to 2012 he was the official dj of 106 & Park, the networks most popular show since its launch in 2000.
Prostyle considers his stay at 106 & Park as a "major deal" and "the best thing" he's ever done in his career, because of the access he gained to big-name artist and industry movers.
Eventually, he returned to New York, first on La Kalle 105.9, and then moving on to Power 105.1, New York's #1 Hip-Hop/R&B station.
