- Wade JohnsonDeputy Chief of CommunicationsWade JohnsonDeputy Chief of Communications
Born and raised on the West Side in St. Paul, I am very familiar with intercity life. I grew up in a Latin-American neighborhood. But growing up outside playing in the streets and dirt helped me to stay grounded…excuse the pun. I excelled at team sports and was fortunate enough to play college football at Augsburg College in Minneapolis. I now live in the North East Metro with my wife and our teenage twin girls.
I think the team sport concept has helped me adapt to 28 years in public safety. During my career here at Hennepin EMS, I have worked as dispatcher, paramedic, was elected Secretary of HCAPE which I served for almost 5 years and in 2011, I was promoted to Operations Supervisor, Deputy Chief of Operations and just recently, Deputy Chief of Communications. I want to think I have had a well-rounded career so far.
In my spare time you can find me in the outdoors. I am also the family’s historian in search of our heritage. I love reading and learning about history, particularly American History. I’m a busy father with teenage twins and playing chauffeur.

- Lori SchmidtBattalion Chief of Operations
- Kent KoellnBattalion Chief of OperationsKent KoellnBattalion Chief of Operations
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.
