Our Picturesque Community

Located in the Twin Cities of Festus and Crystal City—with a local population of more than 20,000—you’ll have access to a culturally rich community. From the cobblestone street at Mississippi Avenue in Crystal City to the vibrant restoration of Main Street in Festus, the two towns mingle nostalgia with modern amenities. Top-rated public and private schools are the core of communities throughout the county—along with vibrant new establishments like wineries, and existing shopping; lodging; and dining opportunities. Jefferson County is soon celebrating its bicentennial anniversary, offering many historic sites to visit, as well.

I am blessed to have the opportunity to carry on the mission established by the Sisters of Mercy nearly 200 years ago. We have the privilege of making a positive difference in the lives of our neighbors, families and friends who come to us for care. You never know when you will make an impact on someone’s life."

Krista McKenzie,
