I started in EMS in 1990 as an EMT on the local ambulance in the small town I grew up in. My parents had served on the fire department and ambulance for many years prior and were Advanced Frist Aid instructors, so it seemed natural to start serving at a young age. Eventually the call of the big city (Hutchinson MN) lured me away. I took An EMT-I course and was hired part time at the Hutchinson Ambulance Service. I became a Paramedic in 1997 and took a full time position.
I was hired here at Hennepin EMS in 2002. During my time at Hennepin EMS I have held the position of HCAPE Chief Paramedic Steward and served on several different committees. I have held my current position as a Battalion Chief of Operations since March of 2018.
