In the last 15 years, I have spent half of my time in the criminal justice field and the other half in academia. I have worked as a Special Agent with the Division of Criminal Investigation in South Dakota, and also as an adult and juvenile probation officer at the county and federal levels. I have been at Simpson College since the summer of 2014 and absolutely love teaching students through experience and passion. My research interests presently lie with sentencing practices, to include probation reports, problem solving courts and other therapeutic options. Additionally, I am working on evaluating curriculum for the training of law enforcement officers. I currently teach various criminal justice courses in law enforcement, courts, and corrections, along with the departmental field experience.
