About Frontenac

Frontenac is a small, affluent city in St. Louis County, west of the city of St. Louis. It is served by the Ladue School District and is home to Chaminade College Preparatory School, giving education a strong local presence. Frontenac Plaza and nearby west-county shopping add a commercial layer, but the city's feel is mostly residential and polished. Frontenac feels residential, leafy, and well-kept, with large homes, private schools, and the routines of old-line St. Louis suburbia.
