- Amber BrownDeputy Chief of Community ProgramsAmber BrownDeputy Chief of Community Programs
I am Amber Brown, Deputy Chief of Community Programs. I started my paramedic career in EMS in 1998 and have been at Hennepin EMS since 2002. I worked as a paramedic on the ambulance until August 2013, when I joined the launch of our Community Paramedic program. I continued in the Paramedic/Community Paramedic role until 2015 when I was promoted to Deputy Chief. In my current role, I manage the Community Paramedic program and Community Outreach for Hennepin EMS. I am passionate about getting our patients the right service at the right time, to achieve the best possible outcome for the person’s overall health and to make an impact in all the communities we serve.
- Chad DotzlerDeputy Chief of OperationsChad DotzlerDeputy Chief of Operations
I began my career in EMS in 1995, working as an EMT (Health EAST and North Memorial), while attending paramedic school. In 1997, I was hired as a full-time paramedic at North Memorial Medical Transportation and worked the street until 2001. While my time at North Memorial was rewarding and memorable, I was always intrigued by the “Hennepin aura” and the “Hennepin Way” of doing business. In 2001, I made the decision to experience the “Hennepin Way”, rather than view it from a distance, and worked as a paramedic on the street until 2008 before being promoted to Operations Supervisor. In 2010, I was also charged with managing all areas of fleet operations, which was the beginning of Hennepin’s change in strategy in regards to ambulance design. Since 2010, our ambulances have gone through transformational change with an emphasis on safety, not only for the patient, but also our staff. This remains a high priority for us and we seek to continue to reshape the future. 2018 was a time of organizational structure change for Hennepin EMS, which resulted in moving to the position of Deputy Chief of Operations (Manager), which encompasses managing the Operations division of Hennepin EMS, including Fleet Operations.
- 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.

- 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.

I try to view everyone I meet as a potential customer/VIP. I enjoy sports and the gym as well as spending time with family, friends, and my pets.
