The Multnomah County Sheriff’s Office (MCSO) is committed to creating safe and thriving communities for everyone. MCSO's impact is immense, providing corrections, civil and public safety services to the most populous county in the state of Oregon. MCSO serves four contract cities: Fairview, Maywood Park, Troutdale and Wood Village, and unincorporated areas, including Sauvie Island and the Columbia River Gorge. The agency is also responsible for keeping more than 100 miles of waterways safe.
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 nearly 30 years of service, her commitment to learning every aspect of public safety has propelled her through the ranks of deputy, lieutenant, captain, chief deputy, and undersheriff. She is one of only two Sheriffs to have held dual certification in both police and corrections while serving in office. As Multnomah County’s 41st Sheriff, Nicole is the first woman to hold the agency’s highest rank.
