About Us

Dedicated to providing state-of-the-art services to children and their families, IN S.T.E.P.P.S. has evidence-based teaching approaches that are tailored to each program. We emphasize naturalistic teaching strategies, such as PRT. We believe each child and family is unique. Programs must fit a family’s routines and lifestyle to result in change that can be maintained.

IN S.T.E.P.P.S. provides services in the natural environment and includes parents, siblings, and any key care providers. We focus on functional skills and strongly believe in the power of positive reinforcement and positive behavior support strategies. At IN S.T.E.P.P.S. our goal is to make learning fun for all involved, and to (re)create a harmonious family atmosphere. IN S.T.E.P.P.S. is committed to providing an equal opportunity and professional work environment with ongoing opportunities for learning and growth. We believe that services can only be state-of-the-art when staff are an integral part of the decision-making process, when staff feel heard and appreciated, and when people work together every step of the way. IN S.T.E.P.P.S. uses a team approach and the collaborative process to continually improve programs and services for the children and families we serve.
