Following his studies at the Yehudi Menuhin School and the Royal College of Music, Douglas started his career at The National Theatre on their production of The Light Princess, a musical by Tori Amos. This helped catalyse his love for theatre in all its forms. He has worked both in musical theatre and in plays, including chairs on Amadeus, again at the National Theatre, Committee at the Donmar Warehouse, and The Great Christmas Feast at The Lost Estate, where he also took on the role of Assistant Musical Director in 2022.

From early 2023 until March 2024 Douglas was the Violin/Viola/Cover Conductor chair on Disney’s The Lion King Tour of the Uk, Ireland and Switzerland.

Currently he is the violinist on the Dear Evan Hansen Tour.

Douglas has enjoyed many years of depping in the West End and UK regional theatres on shows such as: Come From Away (UK Tour), Guys & Dolls (The Bridge Theatre),The Phantom of The Opera (Her Majesty’s Theatre), Les Miserables (UK Tour), The Sound of Music (Chichester Festival Theatre) and Bridges over Maddison County (Menier Chocolate factory).

In addition to his theatre work he has worked both as a session musician and with some of the UK’s leading orchestras including: The London Mozart Players, Manchester Camerata, The Philharmonia Orchestra, and The Royal Northern Sinfonia.

In 2014, following the end of his run on The Light Princess, he joined the Southbank Sinfonia fellowship scheme. He has since been happy to return and play with the orchestra, both as an extra for various projects but also as principal second violin on their collaboration with the NT - Amadeus (mentioned above).

Since 2016 Douglas has performed regularly with The Paraorchestra, Charles Hazlewood’s ensemble comprising of both disabled and able-bodied musicians. With this ensemble he has performed in a diverse range of programmes and settings including: performance art pieces such asThe Virtuous Circle at the 2024 BBC Proms in Bristol, recording sessions for Paul Weller, documentaries for Sky Arts, and orchestral performances at various venues across the UK and Ireland.

Whilst primarily a violinist, he can also double on the viola, mandolin and some basic guitar and piano. He has a baritone voice and professional experience as both a conductor and assistant MD.
