Tara Wasiak - Interim Director

Headshot of Tara Wasiak

“I’m thrilled and honored to serve PBOT in this role,” said Tara. “Not only is PBOT a great place to work, but the work of our bureau, our collective effort to get Portland moving toward a safer, more accessible, more equitable future is an exciting and energizing mission. I am very proud to be a part of this team and associated with this transformational  work.”

Prior to being appointed Interim Director in January 2023, Tara was PBOT's Deputy Director and, before that, was group director of Maintenance Operations. In the latter role, she was involved in advancing PBOT’s equity goals by diversifying the Maintenance Operations workforce. Pre-Covid, she helped organize a career fair for jobs in Maintenance Operations. It was a massive undertaking and they reached larger audiences by rethinking how to advertise jobs and bring people into the bureau. “People don’t know the variety of things we do,” said Tara. The job fair gave them a chance to show participants all of the different opportunities there are at Maintenance Operations.

Another major area of focus for Tara was better integrating Maintenance with the rest of the bureau and improving project delivery for small capital project work. Tara led a reorganization of Maintenance Operations and aligned resources better around all of the groups. She added two divisions and created new positions to be more efficient in how Maintenance delivers the work and supports employees. She wanted to make sure that staff would be better supported in terms of opportunity and professional development.

All of these experiences inform Tara’s work as PBOT’s Interim Director. She will continue to support PBOT in reducing its silos and being more transparent. This includes considering how PBOT delivers its work and how it’s aligned with our strategic plan.
