This is a newly launched website for the City of Petaluma.  Please excuse us as we make it perfect. And, let us know what you think.

Information Technology

Our group handles everything tech. And that doesn’t mean just the computers and phones. It also means the traffic lights, police body cameras, the city’s Finance system and much more. As the world demands more technology and immediate communications, we buy, install and maintain the equipment that makes that possible.

If there was ever a job that required ongoing training, this is it. Just when we got the new finance system up and running, we pivot to upgrade the equipment that records City Council meetings. All the while helping each of our staff stay productive and efficient with the equipment they use daily. We staff a help desk for staff and we are on call 24 hours to make sure mission critical systems are running around the clock. While we stay busy keeping Petaluma in the 21st Century, we love to keep up with new tech innovations and discuss the many ways we can adopt it to help our colleagues and community get work done better and easier.


Tim Williamsen has served as information technology manager for the City of Petaluma for nearly 20 years. A professional engineer and former licensed electrical contractor, Williamsen earned his B.S. in electrical engineering from Washington State University.

"The IT Department plays an integral role in safeguarding the city's information assets and infrastructure. We work behind the scenes making sure that staff have the technology they need to be productive. Our motto is to provide excellent service to our colleagues so that they can provide excellent service to the public."
