Apr 16, 2010. /Lesprom Network/. Derrick Lindgren, the new mill manager for AbitibiBowater's Fort Frances mill, will begin his new job on April, 19. Derrick Lindgren is leaving his role as the manager at AbitibiBowater's Iroquois Falls mill to take over the position in Fort Frances, as ForestTalk reported. John Harrison left his position of mill manager in Fort Frances to join AbitibiBowater's Operational Excellence Group. His new job role will see Harrison overseeing the optimization of all kraft operations and the improvement of overall equipment efficiency. He will continue to be based out of the Fort Frances mill, but his mandate will go beyond that local operation. In Iroquois Falls, Jean-François Guillot will be taking over the job as a manager. For the next few months, Jean-François Guillot will be splitting his time between Iroquois Falls and Bridgewater in the U.K. where he currently is the site manager.
