Stuart and James Parkin joined Hiatco, a designer and manufacturer of access and maintenance systems, in 2001 after finishing college.
The pair were taken on as apprentice engineers and quickly climbed the career ladder, before being offered director roles with the company.
The 32-year-olds will now be jointly responsible for the day-to-day running of the business, which is headed up by managing director Paul Sun.
Paul’s father purchased the business in early 2003 after being brought in to nurture and re-build it during difficult times.
Stuart said: “I never thought when I joined the business that one day I’d end up running it. My dad was a welder so that’s what I wanted to be. Once I started at Hiatco I loved it so I made sure I took all of the opportunities that came my way.
“It just shows that apprenticeships can lead to great things and I am now looking forward to the challenge of running the business and repaying the faith Paul has shown in me and my brother.”
James echoed his brother’s comments, saying: “We’re only a few weeks into our new director roles and I am loving it.
“Yes the pressure is far greater because it’s us at the top of the tree, but because we’ve been here so long and worked in all areas of the business, we know how eveything works and the challenges and priorities for Hiatco.”
Managing director Paul Sun added: “This is an important time for us as we look to take the business to the next level and over the coming months we are making a number of changes and appointments to enable us to achieve this.
“The twins have done a fantastic job since they started with Hiatco in 2001, so for me there are no better people to step up and manage the company on my behalf. I know they’ll do a fantastic job and help the business break into new markets, which we know we’re ready for.”
Hiatco is based at Annfield Plain in Stanley and employs 16 people.
