Aroostook County Sheriff

Peter Andrew Johnson currently serves as the Sheriff of Aroostook County. He was appointed to the position by Governor Janet Mills on September 1, 2023. Following his appointment, he ran for election in 2024, was elected by the voters in November, and officially took office as the elected sheriff on January 2, 2025. 

As Sheriff, Peter is dedicated to fulfilling the mission of the Aroostook County Sheriff’s Office: protecting the lives and property of the people it serves, reducing both the incidence and fear of crime, and enhancing public safety for residents and visitors throughout Aroostook County. He is equally committed to ensuring that inmates are housed in a controlled environment that is safe, humane, and cost-efficient. Peter strives to carry out these responsibilities with honor and integrity while maintaining the highest ethical standards and preserving the public’s trust. He hopes to continue serving the people of Aroostook County and plans to seek re-election in November 2028. 

A lifelong resident of Aroostook County, Peter was born in Presque Isle and raised in Crouseville. He currently resides in Presque Isle. He graduated from Washburn District High School in 1992. 

After high school, Peter attended the University of Maine at Presque Isle while working full time. In 1998, he graduated with an Associate Degree in Criminal Justice and a Bachelor’s Degree in Behavioral Science. For nearly a decade following graduation, he worked in the social services field, serving in several roles including Children’s Case Manager, Registered Alcohol and Drug Counselor, and a supervisor working with juveniles involved in the Department of Corrections. 

Peter began his career in law enforcement in 2008 when he joined the Presque Isle Police Department as a full-time Patrol Officer. In 2012, he was selected to serve as a Special Agent with the Maine Drug Enforcement Agency. 

In 2014, Peter accepted an opportunity to join the Aroostook County Sheriff’s Office as a full-time Patrol Deputy. After one year, he was promoted to the rank of Detective. He later returned to patrol duties and served as Patrol Sergeant in 2018. In December of that same year, he returned to the Maine Drug Enforcement Agency as a Supervisory Special Agent. In late 2022, Peter was promoted to Patrol Commander for the Aroostook County Sheriff’s Office, a role he held until his appointment as Sheriff. 

Beyond his leadership within law enforcement, Peter remains actively involved in the community. He serves on several boards throughout Aroostook County, including United Way Aroostook, the Hope and Justice Project, and Community Action in Aroostook, Washington, and Hancock Counties. 

Through his professional career and community service, Peter continues to demonstrate a strong commitment to public safety, ethical leadership, and the well-being of the communities he proudly serves.
