Swizzy, aka Kasseem Dean in birth, was always about art even in his youth. Born on August 30, 1978 in South Bronx, New York, his father Terrence Dean found Terrence Dean Entertainment Management that took artists under the company. With the field already established, it was not long that Swizz walked on the entertainment path. While a teen, he often took jobs as DJ at parties, although much of his early work were samples and rather experimental. Luckily, his relative opens the opportunity to produce tracks through a label called Ruff Ryders. He produced his first track at the age of 16 and was soon acquainted to many different and bigger labels like Roc-A-Fella, Shady Records and many more. He was also involved in the establishment of Full Surface Records that will eventually excel greatly later on. The label pointed him as the president and CEO by the time he was 23-years-old.

From then on, various artists like DMX and Eve have been closely associated to him. DMX's 'Stop, Drop' gained popularity and consequently helped people to acknowledge Swizz's name. In 2002, the producer who is of Jamaica and Puerto Rico descent, thought it was the right time to have an album featuring his affiliates. 'Presents G.H.E.T.T.O. Stories' was released in December that year and debuted at #50 on the Billboard Hot 200 chart after counted selling 59,000 copies in the first week. At that point it was unquestionable that his credibility as a producer proved to be a huge factor behind his fame. He was soon tapped to produce albums from singers like Mariah Carey, Madonna, Britney Spears, Jennifer Lopez, Usher, Chamillionaire, Ja Rule, Busta Rhymes, Beyonce Knowles, Chris Brown, 50 Cent, Kanye West, Ludacris, Mary J. Blige and many more.

He married R&B singer Mashonda who gave birth to his son in January 2007. He also has an older son named Nasir. After several years credited as producer only, Swizz was back as a solo artist with his album 'One Man Band Man' that was released under his own label Full Surface Records in 2007. Drag-On, Lil Wayne, R. Kelly, Jadakiss, Ciara and even Coldplay's Chris Martin were more than happy lending their talents for Swizz. First single off the album was 'It's Me B*#@hes' (2006) that invited controversy for its profanity. While people started thinking that the song should not be performed on stage, Swizz mildly answered that they took the song "too seriously". In August 2007, Vibe Magazine named the record 'The Best Rap Album of 2007' while Spin Magazine also boasted the album with three and a half out of four stars.
