Our Philosophy

Sheer love of the job and commitment to children.

At Jumping Jax, we work together with your family and any other involved therapists, coordinators, and educators to develop a treatment plan unique to your child. Together, we'll formulate objectives and goals based on your child's skill level and developmental milestones. With each child we see, we aim to improve self-esteem, attention and cooperative play skills.

Your child will receive services in an intimate and very hands-on setting. We hope to be a resource for both you and your child. As much as we love working with children, our goal will always be to graduate them from our services to be successful, independent and confident.
