The Village of Maineville Police Department came into being in the 1950's.  After years of operating with a Village Marshall, which was actually a Deputy Sheriff on special duty, Maineville appointed its first Police Chief.  Glenn Frazier was chosen and led the department. 

In September of 1970, The Village took the next step with the appointment of Police Chief Joe Lane. 

In 1973, a dispute between Hamilton Township and the Warren County Sheriff resulted in the loss of County coverage.  In an emergency meeting of the Maineville Council, an agreement was made to have the Maineville Logo affixed to the township cruiser and Maineville began providing police services to the residents of Hamilton Township.  Soon thereafter, the County resumed normal patrols and the Village returned to patrolling within the Village only.

In 1997, Chief Lane was promoted to Full-Time Status by the Village council.  Within 3 years, it became evident that the income generated by the Police Levy was not enough to cover the salary of Chief Lane, and cover the day to day operations of the department.  To maintain the police department, the Village made significant transfers from the General Fund.

In 1999 and 2000 the Village sought to renew the existing police levies.  After numerous failures of both the Village General Operating Levy (General Fund) as well as the Police Operating Levy, budgets cuts began.  After months of review and input, the Council moved to revoke Chief Lanes full time status, and eliminated the auxiliary officers to save on insurance costs. By the end of 2000, the Village was forced to eliminate the Police Department and contract out services with Hamilton Township.  Due to the financial condition of the Village, the Village arranged for Maineville Police property to be given to the township in lieu of monetary payments. Once all property that could be used by the township was exchanged, the Village was forced to turn to the Warren County Board of Commissioners to meet the financial obligation to the township.

In 2001, The Village enacted an Earned Income Tax Ordinance of 1% which now funds all Village departments except the Street Department.  We continued to contract on a year by year basis with the Hamilton Township Police Department.  In August of 2004, while still under contract with the Township, the Village sat aside $ 50,000 to begin building the new department. In January 2005, the Village appointed Andrew Roosa as Chief of the new department. The Warren County Sheriff's Office donated a cruiser which was painted free of charge by Carstar of  Blue Ash.  A 2005 vehicle was ordered but delivery was delayed until April. By March of 2006, the Village began providing routine police patrols once again, with the Sheriff's Office providing additional support.

Due to external matters, Chief Roosa resigned in 2006, and the process of replacing him began.  After several months of information gathering, interviews were conducted and it was recommended to the Mayor and Council to hire Sgt. John Reynolds as the new Chief.  Council agreed and the appointment was made in August of 2006.
