Occupational therapists help people do the things they want and need to do in life through therapeutic use of daily activities, or occupations. An occupation is anything you do that takes up time and is meaningful to you, therefore everything you do, from brushing your teeth to mountain climbing, is an occupation. Occupational therapy is a holistic process and clinicians are trained to address both physical health and mental health as well as contextual and environmental factors when working with clients. Occupational therapists enable people to live their best lives by helping them promote health and prevent, or live better with, injury, illness, or disability. Occupational therapists must obtain at least a master’s degree and pass a national board certification to practice occupational therapy.
