The Pasco City Council welcomed City Manager Herald Stewart officially on Monday, Aug. 18. Stewart was selected by the council after a nation-wide search, and an indepth interview process held by the Pasco City Council.

“It’s great to be here – I’m excited. I’ve been impressed with the Council, the staff, and the citizens that I’ve met,” Stewart told City Council at the August 18 meeting. “I have an open-door policy, and would love to meet with any citizens that just want to know their government better.”

“También hablo español,” he added, “entonces les invito a visitar conmigo.”

The Council unanimously moved to appoint David Milne as their new mayor, replacing Pete Serrano, who resigned his District 4 Council seat a week prior, after serving the Pasco City Council since 2018.
