The City of Yellowknife announced some changes to its administrative staff Wednesday night.

At his own request, Dennis Kefalas will be leaving his post as the city’s senior administrative officer after almost four years in that role.

Effective October 10, Kefalas will return to his previous role as director of public works and engineering.

Chris Greencorn, the current director of public works, will assume a managerial role in the same department at his own request.

All transfers have been approved by Mayor Mark Heyck and council.

“These changes will allow us to retain these veteran employees’ considerable skills and corporate knowledge which will help us to continue to provide residents with a high level of service in public works operations,” said Heyck.

Kefalas has worked as the city’s senior administrative officer since November 2012 when he accepted an acting position. The job became permanent four months later in March 2013.

An engineer by trade, Kefalas made the request to transfer back to public works when the director position became available earlier this month.

Kefalas will continue to serve as acting senior administrative officer until his position can be filled.
