In 2007 John scored a UK top 20 hit when he was the lead singer for the band Protocol, which was signed to Polydor Records (Universal Music Group) and in 2012 he became a semi-finalist on The Voice with Will.I.Am. His musical past always saw John combining his love for music and fashion styling, not only for his own projects but also that of other artists such as Lana del Rey. After working as a stylist, in 2010 John began working as a PR and Events Specialist which saw him work on projects such as the Net-A-Porter “Summer Party” launch.

He then went to American Apparel where he worked as Sales Coordinator for the UK and Europe for two years, being promoted to Head Office after just 6 months due to exceptional sales in-store. During his time there he was the team leader for projects such as the opening of new retail stores and large scale pop-ups in the UK and Europe. 

In 2012 John started working for Inexcess Fashion, responsible for American Vintage, taking the brand to the next level in the UK, continuing to grow the existing business, resulting in sales growth of 170% per year and closely working on brands By Malene Birger, Custommade, Lollys Laundry, Becksondergaard and Mads Norgaard. His growth resulted in American Vintage opening their first flag-ship London store, which John helped set-up in August 2015, in Westbourne Grove, Notting Hill.
 

In January 2018 John launched his own agency, TCB.
