He has created programs and platforms for CTOA’s young people and become the person they feel comfortable talking to when things aren't working out at home, with their friends or at school.

Christian’s music career started off at church, before moving in 2009 to bands such as latin band Calle Latina, ska band Yebiisu then Three Houses Down (3HD) in 2011. Christian's horn section (Brass4sho - Horn Section) made a name for themselves in the reggae scene playing for 3HD, Sons of Zion and Katchafire at the One Love Festival in 2015 and 2016.

Christian studied at SAE to advance his audio engineering expertise and has worked with the Pacific Music Award winner Vince Harder and Vodafone Music Award winner Stan Walker (and still works with them today).
