Chief Mike Marshman - Biography

Chief of Police: June 27, 2016 - Retired August 25, 2017

Portland Police Bureau Hire Date: April 25, 1991

Mike Marshman was appointed to the Portland Police Bureau in 1991 after working two years for the San Diego Police Department. His motivation for entering the law enforcement profession was centered on helping people who are in need no matter what their circumstances. This has led to an expansive career of assignments in tactical, supervisory and administrative positions.

Mike's executive leadership skills were honed through challenging duties, including increasing internal accountability by overseeing officer-involved shooting investigations. As the Public Information Officer, he acted as the Bureau’s spokesperson as well as developed the current Communications Unit. As Executive Officer for two Assistant Chiefs and as an Acting Assistant Chief, he attained the skills to effectively navigate all the complex nuances of executive leadership impacting the entire Police Bureau.

The Department of Justice Settlement Agreement was being negotiated when Mike was promoted to the rank of Captain. He immediately realized that was an unprecedented opportunity to change the police culture and introduce a fundamentally different way of policing for the City of Portland and its residents, and a fundamentally different way of managing and leading the organization. For this reason, he requested assignment as the point person for the Bureau, liaising with the DOJ. In this leadership role as Compliance Coordinator, Mike managed compliance in five core areas: community engagement, training, accountability, behavioral health and data systems. Additionally, he oversaw policy writing and co-authored most of the DOJ-related Bureau policies.

Mike understands and appreciates the importance of fair and respectful community engagement, as well as accountability and transparency, as the cornerstones for building police legitimacy and public trust. He also believes that the internal legitimacy of management must be strong as a critical ingredient for strengthening external legitimacy with the public and giving officers both direction and support during this local and national crisis when “de-policing” can occur. Officers need strong supervision and consistent accountability. They need clear direction to engage the public in new ways.Mike successfully implemented the groundbreaking Neighborhood Involvement Location (Ni-Loc) program, which uses computer aided dispatching to direct officers to positively engage the community while also providing accountability and performance measurement metrics.
