Hello students, staff, and families! My name is Deputy Mike Erdman and I am the School Resource Officer for the Pine Island Elementary, Middle, and High Schools. My job mission at the schools is to promote a safe learning and working environment along with creating a positive Law Enforcement presence.


I am a current employee with the Goodhue County Sheriff's Office, which I started in December of 2017. I first began working day shift on patrol and then was given the opportunity to move into the school position full time in June of 2019. I am also on the Goodhue County Sheriff's Office search and rescue team as a diver. 

Before coming to Goodhue County, I started out at Crystal Police Department as a Community Service Officer and the Dodge County Sheriff's Office as a 911 Dispatcher. From there I became a part time Deputy with Dodge County and a Police Officer with the West Concord Police Department. I spent 4 years working full time for West Concord, in which part of my duties was being the School Officer for the West Concord Charter School twice a week. From there I decided to move forward to a larger size agency and was given the great opportunity to come to Goodhue County!

My wife and I have been married since 2015 and we have 2 boys. We also have 3 dogs and 2 cats so you can imagine our house is constant craziness! I spend most of my free time with my family going camping, fishing, and hunting, but we also enjoy our quiet nights in catching up on movies and sitting around a bonfire! I also enjoy playing the drums and guitar as well. For those wondering, my wife works in the emergency medical services as an EMT on two different ambulance agencies. She also assists with coaching Pine Island girls softball.


Associate Degree- Law Enforcement- Rochester Community and Technical College 

Bachelor's Degree- Criminal Justice Administration w/ a certificate in Security- University of Phoenix


I have an open door policy, which means if any of our students, staff, or families have a problem they want to talk to me about, I welcome them to stop in any time! My office is easily located in the main office area of the high school building, room 100A. I also have a desk in the main office area at the Elementary school. I want to ensure that everyone knows they can feel free to approach me any time if they need something. No problem is too small!
