Posse History Formed in 1952, the Mounted Posse is incorporated as a non-profit organization and donations to the Posse are tax deductible. There are no public funds used to support the Posse. The Mounted Posse continues the grand tradition of the old west by providing volunteer law enforcement services to the Sheriff. Visitor to the parks, campgrounds and hiking trails are grateful for the Posse's presence because they make them feel safer. Participation Patrols are a major part of the Posse.
Parades are great fun and bring communities together to celebrate special occasions.
The Posse participates in many parades each year including the Rose Festival Grand Floral Parade. Membership Membership in the Mounted Posse requires a significant commitment to training and service to the community, as well as a financial investment. Each Posse applicant is screened by the Sheriff's Office with the same criteria as a Deputy Sheriff applicant. New members attend the Multnomah County Reserve Academy for 300 hours of classroom and field training. On-going training in CPR and First Aid, Search and Rescue, and Firearm qualifications is required.
