Community Involvement

One of our business initiatives is to be a positive influence to our community. Each of our employees is encouraged to set a personal community service goal. In addition, our family of communities participates in or sponsors a variety of local, regional and national charitable initiatives.  

Recent initiatives have benefitted St. Louis Area Food Bank, the Joshua Chamberlain Society, Coat-A-Kid, Toys for Tots, SSM Cardinal Glennon Children’s Medical Center “Rock A Stocking” and more.

In this way, we are giving back to the communities we live, work and play in.
