Sgt. Mark Olsen (retired)
Sergeant Olsen began working at the Cache County Sheriff’s Office in January 1981. Throughout his career, Mark served in Corrections, Patrol, Investigations, Civil, and School Resources. As a sergeant, he supervised patrol and later led the School Resource Division.
As a deputy, Mark was approachable and consistently willing to assist with both professional and personal matters. As a supervisor, Sergeant Olsen supported his team and encouraged high standards, particularly in report writing and public interactions.
Sergeant Olsen retired after 22 years of service. He will be fondly remembered for his positive demeanor, dedication to the profession, and commitment to mentoring younger deputies.
We extend our heartfelt condolences and ongoing support to his wife, Lucy, and their family during this time.
Mark's services will be on April 11, 2026, in Young Ward.
