Sam grew up with his parents, who owned a local pub. However, his dad left home when Sam was just 11, so he was forced to help his mum more with the bar. He had early sexual encounters, and he came out as gay at 16. Despite being intelligent, Sam left school with few GCSEs, planning to become a famous DJ. He eventually became a volunteer at hospital radio. He had a twice weekly spot. This experience made him realise what working in a hospital was like, inspiring him to go into medicine. He decided to train as a nurse.
