About us

    Kristina Vanderheyden Loudon

    FOUNDER + DIRECTOR

    Kristina (she/her) created Street Theatre in 2020 when the world stood still. Seeing creatives out of work and communities missing ways to celebrate special moments, she set out to bring the arts to doorsteps.

    In the years since, Street Theatre has evolved into much more. From working in prisons to collaborating with incredible corporate clients and creating unforgettable adventures for children’s parties, the heart of the company has remained the same, spreading happiness.

    Kristina spent over a decade in the world of technology before embracing her true passion, creating experiences full of imagination and joy, which is quite fun as a mum of two young children.
