Thrive Boxing Team, which was founded in 2023, said it helped children and young people build resilience, confidence and a sense of belonging inside and outside of the ring.
Ms Norfolk, who is its founder and lead coach, got into the sport after experiencing addition.
She said boxing became the “turning point” and gave her structure, discipline, “and something bigger to fight for”.
Ms Norfolk, who is also a social worker and manager within child and adolescent mental health services, said the sport allows her to build trusting relationships with her students.
One young boxer with a history of criminal offences became a part of the club and “changed their life around”, Ms Norfolk said.
Another one of her students told the BBC: “She is not just a coach she is like a mum as well and it is nice to have her.”
Ms Norfolk said: “We create a really good culture, we celebrate diversity here, and every single person who walks through the door, who might feel a little bit nervous or uncomfortable, always walks out feeling like a champion.”
