About me

I am a Deputy Prosecuting Attorney in Benton County in the Felony division. I focus on prosecuting domestic violence, felony traffic offenses, property crimes, drug crimes and adult sexual assault crimes. I have previously worked in civil litigation focusing on personal injury representing plaintiffs. I am active in the local Benton Franklin County Bar Association, SE Washington chapter of the Washington Women Lawyer's group, and I volunteer on the Benton County Park Board (secretary/treasurer) and City of Kennewick Parks and Recreation Commission.
