Overview of the Biscailuz Training Center
The Biscailuz Training Center, a 36,000-square-foot facility, has been a cornerstone of sheriff deputy training since its reopening in 2017 after renovations. Originally operational from 1946 to 1984, it was closed due to space constraints before being modernized. The center houses specialized units, including the bomb squad, which handles explosives across the region.
