Meet Jim Arnott

candidate for sheriff

With 32 years of experience, Jim Arnott knows the law and the people of Greene County, MO. His specialized education and training in investigations, weapons and tactics have allowed him to serve as Greene County’s working sheriff since 2009. While overseeing the largest sheriff’s office in Missouri, Arnott has established new programs, expanded available resources and taken an active role in work on the ground. 

Goals for sheriff’s office

What’s Ahead in 2021?

In 2017, Greene County taxpayers approved a 1/2-cent sales tax to build a new county jail. The Greene County Sheriff’s Office will move to northwest Springfield and provide more than 200 new jobs. Breaking ground on the state-of-the-art $155 million facility begins April 2020. 

The building is projected to be completed in two to three years. 


One Sheriff’s Story

Jim Arnott is a 30+ year veteran of the Greene County Sheriff’s Office. During his tenure with the Sheriff’s Office, he has worked in all aspects of the patrol division and in various detective units. While working in this capacity, he was the lead detective on multiple homicide and high-profile investigations. As a detective, he was promoted to Detective Sergeant, Detective Lieutenant and finally to Detective Captain. In 2006, former Sheriff Jack Merritt promoted him to Chief Deputy.


Sheriff Arnott is a certified instructor for the State of Missouri, and he teaches at the Drury University Law Enforcement Academy in Springfield, MO. He holds a Bachelor of Science in Criminal Justice Administration from Columbia Southern University and was the first deputy from the Greene County Sheriff’s Office to attend and graduate from the FBI National Academy. Only 1% of law enforcement officers are able to attend and graduate from this elite academy.

He graduated from the 97th session of the National Sheriff’s Institute. Arnott has continued to build upon his education to better serve Greene County. In 2013, he attended the Chief Executive Leadership Program at the Southern Police Institute. 

Life As Sheriff

Arnott is dedicated to the citizens of Greene County. He is a community volunteer and crime victim advocate. He and his wife, Jennifer, have two children.

The Greene County Sheriff’s Office is where he started his career, and he continues to serve the organization and its community. In November 2008, he was first elected as the Sheriff of Greene County Missouri and was re-elected in 2012 and 2016. 

Sheriffs from across the state of Missouri elected Arnott to serve as President of the Missouri Sheriffs’ Association from 2018-2019. This non-profit organization supports sheriffs and their vision for safer communities through legislative efforts, as well as training and technical assistance.

The A&E documentary “Live PD” featured Arnott and the Greene County Sheriff’s Office for two years. During the summer of 2019, the show had a record-breaking 2.4 million viewers. 

As sheriff, Arnott’s responsibilities include but are not limited to the patrol of Greene County’s unincorporated areas, the patrol of county roads and highways, inmate housing, serving of civil process, investigation of crimes, and courtroom security.

In June 2020, Arnott was honored in the 10th annual class of Springfield Business Journal’s Men of the Year.
