As a recreational therapist assistant, you support a primary therapist while providing therapy and care for clients or patients. You may help set up and run a therapeutic activity or treatment, examine the behavior of patients, help implement clinical treatments, or conduct a psychological assessment to gain a better understanding of the unique needs of each patient. Recreational therapist assistants often specialize in specific groups that use recreational therapy, such as children or veterans, and which group you work with may impact your career opportunities and path. Most recreational therapist assistants work regular hours, but employers may occasionally ask you to work overtime to help address particularly complex or difficult cases.
