Meet the Team

The Gibson Center for Behavioral Change is committed to providing comprehensive services which promote new behaviors for a healthy lifestyle. Our Leadership Team works hard to provide a positive and welcoming environment in our facilities and among our staff.

Gibson Center for Behavioral Change employs some of Missouri’s leading addiction treatment experts. Our multi-disciplinary team functions as a whole to provide a variety of treatments for our drug and alcohol programs as well as our behavioral health-centered programs. We believe that the staff members we employ are just as important as the treatment programs themselves.
