We love the work we do here.
In designing our therapy approach, we have made a conscious decision not to mold your child to fit into our environment, but rather to teach your child strategies to function and communicate in all environments.
Our jobs are meaningful and purposeful-we know how to help! Red Door addresses functional, behavioral, emotional, and social development while incorporating fun and innovative activities.
