Judge Teresa Estrada-Mullaney has announced she will retire from the San Luis Obispo Superior Court on Jan. 25, according to court officials.
Estrada-Mullaney, a Democrat who turns 65 in December, has been a county judge since her appointment in 1992.
She worked as a deputy district attorney in Orange County from 1979 to 1981 before she was hired by the San Luis Obispo County District Attorney’s Office, where she worked as a prosecutor for 11 years.
Estrada-Mullaney was the county’s first female judge and the first Hispanic judge since the 1800s.
Her current assignment is criminal court, but Estrada-Mullaney has also presided over civil, family and juvenile cases during her 20-year career on the bench.
