The government of Wentzville consists of a mayor, six aldermen (two for each ward), and a city administrator.

As a result of the contract, Serco opened its Affordable Care Act application processing facility in Wentzville in August of that same year in the building that was formerly home to the US Fidelis call center.

The Wentzville Serco facility attracted national attention in 2014 after whistle-blower allegations revealed that workers spent large amounts of time sleeping or playing games due to lack of work.
