Owner Peter Casey has appointed his son, Chris, as managing director of Rochdale-based building and environmental development firm, the Casey Group.
To make way for Chris, who will begin his new role on 8 April, Tony Chell has moved to the position of chief executive and will concentrate on strategy and special projects.
Peter Casey said: "In a total re-appraisal of our present management structure we have assessed who would be best placed to take the business forward to the next dimension."
Chris Casey said: "The past few years have been a really challenging time for us but I am excited about taking on this responsibility.
"Casey is a family business and this allows us to think and act with the long term in mind. As Peter has said previously, long-term business friendships are more valuable than short-term business gains. I am committed to maintaining those relationships and ensuring that we continue to grow our reputation and presence in the construction, environmental and ancillary sectors."
The Casey companies have a history of projects in construction, land reclamation, public realm and environmental works, developments and construction plant hire.
