Wyoming, Michigan, November 26, 2025 – Following a distinguished career with the City of Wyoming spanning three decades, Wyoming Public Safety Chief Kimberly Koster has announced her retirement, effective Jan. 2, 2026.
Chief Koster has served in her role since April 25, 2018, leading a team of nearly 167 full-time sworn and civilian personnel from both the police and fire department, During her tenure with the department, she built a strong foundation of community trust and led her team to serve and protect through violent crime incidents, medical emergencies, severe weather, two public safety ballot proposals, an unprecedented global pandemic, among others.
Under her leadership, Chief Koster:
- Played an integral role in passing a public safety millage proposal – supporting the addition of 14 new police officers and 13 new firefighters, opened and renovated all four fire stations to provide quick and professional service to all districts in Wyoming, purchased a new platform fire truck to respond to multistory building fires and combat violent crime with proactive policing.
- Worked to maintain and secure accreditation for the Department from the Commission on Accreditation for Law Enforcement Agencies and was appointed to serve as a commissioner with CALEA.
- Was appointed by Governor Gretchen Whitmer to the Michigan Commission on Law Enforcement Standards to represent the Michigan Association of Chiefs of Police.
- Developed strong relationships with the business community in Wyoming by implementing a second shift community services unit that provides proactive and overnight policing in the City’s business districts.
“Chief Koster has been a significant asset and leader not only within our City offices, but especially for our residents, whom she has built countless positive relationships with,” said Wyoming City Manager John Shay. “I’m deeply honored to have served with her and am incredibly proud of her accomplishments and contributions to improve Wyoming.”
“I know that I speak for all of us at City Hall and the Department of Public Safety in wishing her and her family the best as she begins this next chapter.”
With three decades of law enforcement experience, Koster began her career with Wyoming as a school resource and community policing officer. In this position, she worked with neighborhood groups and organized community events to bridge gaps and build solidarity among neighbors.
She worked her way up through the ranks to detective, sergeant, lieutenant and captain, a position she had held since 2010. In this role, she assisted with the formation of the Public Safety Department through the administrative consolidation of police and fire services, created a new staffing model, facilitated dispatch operation transitions and led a collaborative effort in the development of the department’s five-year strategic plan.
“The departure of Chief Koster is tremendously bittersweet,” said Wyoming Mayor Kent Vanderwood. “During her tenure, she has consistently demonstrated exceptional professionalism and leadership, along with remarkable energy, passion, and commitment to her profession, her city, and her department.”
“Wyoming City Council wishes her well as she transitions into retirement and we thank her for her incredible service throughout the years.”
City Manager John Shay has appointed Deputy Director Kip Snyder to the Director role. Snyder has served with the Wyoming Police Department for 33 years as an officer, K9 handler, vice detective, sergeant, lieutenant, captain and most recently as Chief Koster’s Deputy Director. He will remain in this role until his retirement.
In her letter to City Manager John Shay, Koster wrote: “The City of Wyoming is extremely fortunate to have police officers, firefighters, and professional staff who are filled with compassion, capable of heroic action, dedicated to justice and hard work, fair to everyone, and professional beyond measure. Being their Chief was one of the greatest gifts I was ever given…”
Throughout her career, Koster has been recognized with several commendations, including the Life Saving Award, Chief’s Award of Excellence, Outstanding Young Public Safety Officer and Safe Driving Award.
She served as a 911 communications supervisor, during which time she led the consolidation of police and fire operations in multiple communities, including Wyoming’s move to Kent County. She has also served as lead detective in homicide investigations and as a crisis negotiator, among other critical roles throughout her career.
With a commitment to training and development, she graduated with Class 251 of the FBI National Academy. She also attended the Leadership Institute training hosted by Grand Rapids Police Department and the Police and Staff Command training hosted by Northwestern University.
