This week, meet Greene County Sheriff Rob McMillen. . 2010 Tell us a little about yourself I graduated from North Greene High School in 1987, and then attended Lewis & Clark Community College from 1987 to 1989, studying the field of criminal justice. I married my wife, Mona, in 1989. Mona and I have one adult son, Brennan. I began my career in law enforcement in 1990 as a police officer for the White Hall Police Department. In 1992, I accepted an offer to become chief of police for the White Hall Police Department. I served as chief until being elected Greene County sheriff in 2010. Brennan is a police officer with the Jacksonville Police Department, which makes me very proud but also causes his mother to have double the worries — being that not only her husband is a law enforcement officer, but her son is as well.
