ChiefChief Frank T. Selvaggio 

Hi everyone, I was appointed the Chief of Police here on October 25, 2018.  My 40-year career in law enforcement has included over 28 years with the Clayton Police Department and 9 years with the Washington University Police Department.   I have held many ranks including Police Officer, Corporal, Detective, Sergeant, Lieutenant, Bureau Commander, and now Chief.  Some of my most memorable events in this job include being an Investigator for the Greater St. Louis Area Major Case Squad, the on-site Commander for the 2016 Presidential Debate held in St. Louis, attending the FBI National Academy in Quantico, Virginia, and being named the Missouri Police Chief of the Year for 2020 by the Missouri Police Chiefs Association. 

My wife, Jan, and I were married in 1986 and have 4 children and 3 grandchildren. She has been a huge supporter of my career, as being the wife of a police officer is not always easy. My 2 goals as Chief are to do everything possible to make this community proud of their police department and to invest in these officers so that they are proud to serve this awesome community.

I am known to the majority of the community as Chief Frank. 

Fun Fact: I picked up a box turtle off the road one day which turned into a huge effort by every officer here to do the same thing. Our saving the box turtles has become an annual craze, which even generated a full-page article in the Leader Newspaper.
