John N Dunn Group has appointed Darren McCallum as commercial manager, strengthening its electrical division.
Based at the Group’s Newcastle headquarters, Darren’s role will include overseeing site evaluations, contract administration, liaising with the company’s supply chain and being the key point of contact for stakeholders.
In his most recent role, Darren was a quantity surveyor at Taylor Wimpey.
He returns to John N Dunn Group, where he previously worked as an electrical buyer between 2017-22.
Founded over a century ago and headquartered in Newcastle, John N Dunn Group has built a powerful reputation for delivering high-quality mechanical, electrical installation and maintenance services across a wide range of projects, from large-scale construction schemes to reactive maintenance. Serving major UK housing developers, housing associations and commercial contractors, the company operates across the North East, Yorkshire and Scotland, having successfully completed over 7,000 contracts.
Darren said: “I’m really enjoying being back at John N Dunn Group. The company has a strong culture and has retained the feel of a family business.
“There are clear progression routes in place for all who want to develop their careers and I’m looking forward to watching the electrical division grow.
“Working at Taylor Wimpey, I gained invaluable experience which will only assist me in my new position.”
Lee Haddock, managing director at John N Dunn Group in Newcastle, said: “It’s great that Darren has learned new skills since he was last with us and that he will apply this new knowledge to the benefit of John N Dunn Group and our clients. Providing career progression routes is something we are very keen to emphasize throughout the business and while Darren is returning with new skills, there are great opportunities internally here at John N Dunn Group for our people to grow and develop.”
