The Team

We are a team of psychologists, educators, and a physician led by Dr. William Ketterer. We have more than 40 years of combined experience working with and educating children and adolescents. Most importantly we are experienced in implementing Dr. Ketterer’s model. In addition to improving children’s self-esteem and capacity for self-regulation, our approach has the power to enliven and improve classroom and school culture.
