Tibbetts was re-elected for the first time in 2020 but said he had to step down from the council to devote more time to his family and infant son.

MacDonald will serve temporarily until a permanent replacement is elected this November.

According to the city, MacDonald is a fourth-generation resident of Sonoma County and has lived a total of 40 years in Santa Rosa.

She is part-owner of North Bay Commercial Services, a heating, ventilation, and air conditioning contractor. She was also the president of the California State PTA from 2017 to 2019 and currently serves as a legislative advocate for the parent-teacher organization.

MacDonald is also the county representative for the Sonoma County Commission on the Status of Women, the county said, and sits on the board of the Rincon Vallejo Education Foundation. She is also co-chair of the California State Literacy Task Force.

MacDonald was chosen from six candidates.
