Dorsey married Dr. William Dorsey and they are moving to a new home in the unincorporated area of the township.
Township trustees can live in the city, but city council members cannot live in the township.
Dorsey was elected in 2017, running unopposed.
“I love Springboro,” Dorsey said before Thursday’s council meeting. “It’s been good to be a part of it.”
Dorsey is resigning, effective July 31. The council is expected to name her replacement.
