On Aug. 31, O’Fallon Police Chief Roy Joachimstaler announced his retirement from the city’s police department, effective Dec. 7, bringing an end to a nearly 50-year career in law enforcement.
Joachimstaler joined the O’Fallon Police Department in November 2009, after retiring from the St. Louis Metropolitan Police Department in that same year, attaining the rank of lieutenant colonel and serving for 39 years.“It has been an honor and a privilege for me to spend the past nine years serving alongside the professional men and women of the O’Fallon Police Department,” Joachimstaler said in an official release. “Together, we have built a world-class team of officers and civilian employees who are dedicated to serving our residents and keeping our city one of the safest cities in this country.
“Although it is difficult to leave this position, my wife and I know that the time is right for us to move on to the next phase of our lives. But I leave knowing that this department is well positioned to continue to excel in the future and that is because of our incredible leadership team and our dedicated officers.”
While with the St. Louis Metropolitan Police Department, Joachimstaler served as a uniformed police officer in both the 5th and 6th districts, the Mobile Reserve Section and as a detective assigned to the Vice-Narcotics Division. He was promoted to lieutenant in 1987 and served as a watch commander in the 5th and 6th districts. During that time, Joachimstaler also spearheaded the “Foot-Beat Program,” a precursor to community policing.
Joachimstaler later became the commander of the Vice-Narcotics Division. In 1994, he was appointed special assistant to the chief of police and was placed in charge of the department’s community-oriented problem-solving [C.O.P.S.] initiative.
In 1996, Joachimstaler assumed command of the South Patrol Division and took charge of the uniform patrol force and detectives for the southern half of the city of St. Louis. He then went on to command the Bureau of Patrol Support.
In 2003, Joachimstaler was promoted to deputy chief before becoming chief of detectives in charge of the Bureau of Criminal Investigations in 2007. In 2008, he was named to lead the Bureau of Community Policing.
The city of O’Fallon will begin an immediate national search for a new chief. A final determination regarding an interim appointment will be made at a later date if it is determined to be necessary.
