Matt GrummMatt Grumm

Senior Policy Manager

(503) 823-4151  |

Matt has been working with Dan since his first campaign for City Council. He assists the Commissioner in managing the Portland Bureau of Transportation and is a good contact for all transportation planning activities in our region. He's also the point of contact for issues pertaining to city utilities, short term rentals and general Portland government questions. Matt has also advised Dan on numerous city budgets and is an excellent resource for budget information.

Matt has a BA in Political Science from Southern Oregon University and dabbled in urban planning at Portland State University. He grew up in the heart of the Mid Willamette Valley, the sorely misunderstood and great town of Albany Oregon. While in college he interned for Senator Ron Wyden, and after moving to Portland in 1997, became very active in local politics. He is a rabid Portland Timbers fan and will also talk your ear off about the Blazers if you give him a chance. You have been warned.

Additional Liaison Responsibilities: METRO’s Joint Policy Advisory Committee on Transportation, Public Works Permitting processes.
