Meet Nicole Morrisey O’Donnell

Sheriff Nicole Morrisey O’Donnell has been dedicated to public safety service since she began her career with the Multnomah County Sheriff’s Office in 1996. Throughout her more than 25 years of service, her desire to learn every aspect of public safety has propelled her through the ranks of deputy, lieutenant, captain, chief deputy, and undersheriff. In addition, she is one of the few Sheriff's Office members who hold dual certification in police and corrections. As Multnomah County’s 41st Sheriff, Nicole is the first woman to hold this highest rank.
