Biography

I have been at HCMC/Hennepin Healthcare almost 24 years. I have been an EMT for 20 plus years. I started in the security department and moved to EMS 14 years ago. I worked my first 11 years in EMS in a dispatcher role, the last 3 as a supervisor. I truly enjoy helping others, especially on their worst days. 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.

Biography

I started my career in EMS in 1996 with a local ambulance service doing wheelchair and BLS transports. I then transitioned to a Dispatcher role, and eventually dispatched for 911, critical care, and helicopter transports. In 2000, I started working with a local air ambulance provider as an EMT, eventually working my way up to Flight Paramedic. Today I am enrolled at Bethel University and continue to work on my Bachelor’s Degree in Organizational Development & Leadership. I started working for Hennepin EMS in 2015 and never looked back. I am proud to be associated with such an outstanding team of Leaders, Paramedics and Emergency Medical Dispatchers.

Biography

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.
