Ms Marsh gave up her job as a prison psychologist to retrain as a stonemason because she wanted a “manual” job.
“I wanted to do a physical job, where you can be outside quite a lot and it has links to heritage craft and older buildings, which I really love,” she said.
“I thought it was a brilliant way of being able to meet the creative need to be a sculptor but also have a trade and craft I could lean on.
“It was a big leap, and I left and a secure, good job to retrain so it’s been a journey.”
She trained under The Prince’s Foundation’s Building Craft Programme, travelling to heritage sites across the country over eight months.
She said: “It’s really important to listen to what makes you tick. I knew that I got great satisfaction from using my hands to make, and being manual with things.
“Success is a really wide spectrum, it doesn’t necessarily have to be academic. I worked part time for a mental health charity while retraining, so it’s possible, it’s just finding the time.”
