Between 1973 and 2006, Benner was in private practice in Illinois and Ontario. Whereas his clinic-based practice focused on children and adolescents, particularly those suffering from abuse and experiencing dissociative disorders, his private practice focused on adults. Within this context he developed and offered an intensive, highly individualized, short-term (3 week) residential intervention that combined clinical and spiritual components. He offered these
Intensive Soul Care Retreats and trained others to do the same for over 20 years. Benner was Chief Psychologist at Child and Adolescent Services,
