Although keen on the performing arts as a child, Sheridan did not get the opportunity to begin pursuing them as a career until he was almost 40.
He joined the Royal Navy straight from school & served for just under 8 years before being medically discharged.
​
He had numerous jobs after this including: Night Patrol in H.M. Prison Service, Pool Lifeguard, Taxi Driver, Security Driver, & Football/Cricket Safety Steward.

Between 2008 & 2010, Sheridan was performing a Mentalism act under the name Nick Knight, but had to take time out following a back injury & a hernia operation.

In 2012 Sheridan helped his cousin Allan, by acting in some amateur productions, which rekindled his interest in performing.

​ The following year, Allan sought advise on marketing his film works & so was advised to build a Production Company, M.D.P., after the completion of Allan's web-series Waterside Season 1. ​

​
This series is the earliest of Sheridan's role's which is actually available to view online; he plays one of the lead character's, Maximum King.

​In 2017, he was asked to reprise this character for Season 2 by the production team who have taken over the franchise.

​Between May 2013 & December 2014 different team members came & went until MDP became dead in the water, but not before a number of amateur short films & a full length feature were completed. 

​Mass Distortion Production's first outing was the Pilot Episode of the fan made web-series Hitman: Vengeance (2014) & in 2014 the final piece was the full length feature, Remain Humane (2017). 

​Sheridan enrolled with Derby Academy of Acting in September 2013 & has also attended their workshops on: audition technique & sight reading, actioning the text, & stage combat.
​He has also had one to one tuition with the Academy's Director Neale Birch.
​
​In 2014, Sheridan became a member of The Derby Shakespeare Theatre Company where he broke his stage cherry; performing the role of Pistol  in Henry VI Part II, & then later that year playing Sir Henry Dundas in their production of Alan Bennett's The Madness of George III.
​
His third stage performance of the year came in December 2015, when Sheridan appeared as Scrooge in Hothouse Theatre's production of Dickens' A Christmas Carol.

​Sheridan is up for almost any challenge, a good team player, who understands the meaning of commitment & collaboration in any production he is involved in.
​
​When not working , Sheridan spends his time outdoors either riding his motorbike or walking with his best friend Beowulf.
