O'Fallon is the fastest growing city in the Wesplex. Highway K has turned into the ultimate source for almost anything from retail shopping, dining, and other services.
The City of St. Charles is where the Westplex began. Once the capitol of Missouri, St. Charles City has evolved into a great place to live and do business. The City of St. Charles is the county seat of St. Charles County and is also home to Lindenwood University.
