Now after six years, Sarah has returned to the North East to work at the South Shields Community Fire Station.
Sarah said "I always wanted to experience a job with some high intensity and I’ve always loved a stressful project. After University I knew I would never be suited to an office job, so I looked into joining the fire service, but due to a recruitment freeze there was never an opportunity for me to apply so I joined the army.
"I was born in South Shields and left as soon I could because I wanted to experience more, but now I have my own home on the sea front and I want work in and serve the community where I grew up."
Fluent in French, Spanish and Arabic, Sarah joined the British Army as a linguist and translator after initially being rejected by the Royal Navy over a tattoo.
And she is now encouraging other women to get involved in the fire service by sharing her training experiences.
She added: "Being back home to work is lush, you miss out on so much when you are abroad. I'm glad I can go to weddings and birthday parties and be there for my mam. Although the course was stressful, when I look back I just think about all the good times we had, the course is made by the people on it.
Assistant Chief Fire Officer Lynsey McVay, is encouraging more women like Sarah to become part of the fire family.
She said: "Anyone can be a firefighter, you just have determination, commitment, the heart and people at the core of what you do - we can teach you the rest. We hope people like Sarah can help inspire other women to consider a role as a firefighter.”
