A graduate of Falmouth University, Shelly Tregoning has in 2018, for the second time, had her work selected for the Columbia Threadneedle Prize exhibition at London's Mall Galleries. Her paintings have also been on show at the National Open Art Competition, the Discerning Eye exhibition, and the Royal West of England Academy show.

Working from a studio at the Cornubian Arts & Science Trust (CAST) in Helston, she describes her art practice as an exploration of the interior of people, of their deeper identity and selves.
