Stephen Martin Allan studied at Canada's National Ballet School from 2016 to 2018, earning a special scholarship despite having only one year of ballet training prior to that. He graduated with the Special Staff Ballet Award and the Musician Award. His further studies took him to the Guildford School of Acting. His first professional engagement followed in late 2018, and while still a student he choreographed his first work, TIMELESS, working with professional dancers from the Dutch National Ballet School, San Francisco Ballet School, and Canada's National Ballet School. At the time, he was the youngest choreographer working in London's renowned dance studios. With CATS, Stephen Martin Allan makes his musical debut and is one of the youngest performers ever to take on the role of Mr. Mistoffelees.
