CST Training

A CST training team was established in 2014 at The Saint Louis University Gateway Geriatric Education Center. They have recently been designated as The North American Cognitive Stimulation Therapy Training Center (NACSTTC) and are in the early stages of development. Once established, future trainings will be conducted through the NACSTTC.
