As a Devonshire boy, born and bred in Plymouth, Jefferson dedicated himself to pursuing a career in the performing arts from a very early age. In 1999, he joined his local Stagecoach Theatre Arts School and throughout his 11 year journey there played a diverse range of roles in productions from Little Shop of Horrors to devised plays. This sparked Jefferson's fascination in becoming an improvisational comedian alongside his acting career, which later led him into pursuing one of his childhood dreams of becoming a pantomime comic.
He moved to Guildford to develop his craft further at the Performance Preparation Academy, before continuing to study Musical Theatre at the London College of Music with University of West London in 2015. Since then, he has toured around the UK - and performed many successful incarnations of his stage act and stand-up comedy in theatres, hotel resorts and on cruises around the globe.
2023 saw Jefferson make his television acting debut, taking on the younger incarnation of Mark Williams' titular character in BBC's Father Brown - and shortly after roles in Doctors and Britbox's Sister Boniface Mysteries (both also for BBC Studios).
In that same year, he won a place on the world's first year-long Masters degree in Contemporary Pantomime Practice at University of Staffordshire (previously Staffordshire University). Having become one of the first and only people to achieve the MA, with the news of his award gaining widespread media attention last year, he made his Panto debut in the role of Silly Simon in Jack and the Beanstalk at The Corn Hall in Diss, Norfolk with SparkLive Pantomimes.
As a presenter, Jefferson was invited to perform alongside and present awards to some of the UK's biggest pop groups at the 2001 and 2002 Disney Channel Kids Awards ceremonies. Over a decade later, he went on to produce and co-present his self-penned radio show The Jeff Parlett and Benny Bright Show on Blast Radio, broadcasting from the legendary Ealing Studios from 2012 to 2015.
