About Us

Therapeutic Approach to Growth, Inc. believes that when given the appropriate support all individuals with Autism Spectrum Disorders and other developmental disabilities have tremendous potential to become active participants in their community, have genuine relationships, and at times live independently.

For the best results, a collaborative team approach, requiring parent involvement and communication amongst professionals is recommended to ensure all team members effectively collaborate and approach the individual in a consistent manner.

Therapeutic Approach to Growth will make every effort to work together with parents, school districts, and other treatment providers to develop an individualized comprehensive treatment program that functions in the highest interest of our clients.
