When and Why did you join Trinity?
I joined Trinity in February 2021 as a Contracts Manager for one of our large key accounts. I’ve since gone onto various roles within the business. I very much feel at home within the business.
What is your role at Trinity and what does it involve?
My current role is Regional Director Midlands & North, within this role I lead our engineering management team across the region. We strive to deliver service excellence to our large and complexed client base.
What’s the best part of your job?
People and problem solving, I very much enjoy working with and leading others to create solutions to problems and driving positive outcomes. That’s what makes me feel good at the end of each day
What kind of challenges do you face in your role?
Fire & Security has an industry problem which many businesses of facing at present, which is a lack of good technical engineers within the industry. At Trinity we are proactively working hard to nurture our own engineers of tomorrow with our apprenticeship program. I’m a massive advocate of apprentices in the industry having been one myself.
Tell us an unusual fact about yourself?
Nothing springs to mind straight away as being massively unusual. However, I did recently bump into Thomas Tuchel (quite literally) at St Georges Park recently. I was too busy reading something on my phone and walked into him. The guy is massive. He and his team were absolutely great.
