After completing my professional degree in commercial refrigeration and spending two and a half years in an Engineering and Design office, I was eager to return to fieldwork.
I joined ETT in January 2024, and what I love most about my job is troubleshooting and finding solutions on diverse project sites.
It's a career where you're never bored!
When I arrived at ETT, I was impressed by the long-standing employees - some with 35-40 years of service. It's reassuring. I appreciate the overall friendly atmosphere within the company.
The Bretons are very welcoming. Colleagues are easily approachable, and even though I'm far from headquarters, everyone is readily available if I have an issue.
I feel fortunate to have found my calling.
