When and Why did you join Trinity?

I joined Trinity in April 2017 and , after working within the Electrical Contracting industry for many years, I wanted to work within an associated industry in order to further my career progression, whilst also gaining new opportunities within a growing company.

What is your role at Trinity and what does it involve?

My role at Trinity incorporates elements of both Works & Sales, all relating to the newly strengthened presence on the South Coast region. The combined role, and its associated challenges, are one of the main reasons my new role proved to be so appealing.

What’s the best part of your job?

Working alongside the charismatic David Town!

What kind of challenges do you face in your role?

I joined Trinity from a smaller company therefore using new software such as Focal Point & Alarm Master has proved to be quite challenging. Thankfully after a few short weeks, and with some training on the software, it’s all starting to come together now.
