In October, KOSSERER, OBOS league club, confirmed in a press release that Mark Dempsey's main coach was notified indefinitely.
Manager Espen Nystuen took over as the lead coach in the season.
On Tuesday it was known that Mark Dempsey acted as the lead coach immediately.
Originally, the English had contracted the 2020 season with the club.
"I can confirm that we have moved back to England. As most people say, I have not really felt recently, and our daughter, Maisie, has felt that things have been heavily. After careful and long consideration, we have decided that the best thing is to move home, says Mark Dempsey to Glåmdalen.
Mark Dempsey has a long career as a football coach behind him.
Y Saeson was the lead coach and assistant instructor at Haugesund, an assistant coach at Molde, the main Swedish Djurgården coach and the head of a trainer at Start.
He took over Kongsvinger in July after being burned at Start. Now Kongsvinger must look for a new lead coach.
– The contract has terminated after KIL and I reached an agreement. But I must emphasize that Espen (Nystuen) has been very supportive and understands through this difficult time, and I'll appreciate that, says Dempsey to Glåmdalen.
Kongsvinger ended at eighth in the OBOS League this year with 42 points.
