The board voted unanimously on Dec. 8 to appoint Thomas Galvin to the seat.
It has been open since Steve Chucri’s resignation went into effect Nov. 5.
The District 2 seat will be on the ballot during the November 2022 election.
The board selected Galvin from among seven finalists after conducting interviews last week.
Galvin is a member of the Rose Law Group’s land use, government affairs and renewable energy practice groups.
He grew up in New York and has lived in Arizona for about 14 years.
Galvin previously worked as a policy adviser to Brenda Burns when she served on the Arizona Corporation Commission.
