We founded Partner in Wellness in St. Louis based on our shared values of family (yours and ours), balance, quality of life and adventure. We strive to be a resource for the community through education, creativity, and quality care.  An eating disorder can be a barrier that stands between a person and the life they truly desire. We are passionately committed to treating the disorder and removing the barriers so our clients can pursue their passions.
