Dan Brickheimer
Classroom & Behind The Wheel Instructor
I retired from the Marathon County Sherriff's Department as a Detective with 27 years of Law Enforcement experience. Before I began law enforcement I had 5 years of truck driving experience and had logged miles in over 30 states. Dan's unique knowledge of traffic law, accident investigation and emergency vehicle operation make him a welcome addition to our staff. Dan and his family have lived in the Marathon area for over 20 years.
