Our Mission

Our experiences in working with many therapy techniques and years of helping children around the world have inspired us to share our knowledge with as many therapists and families as possible. Our goal is to make quality therapy readily accessible for children and their families and to teach this dynamic method to therapists around the world.

Experience and Professionalism

With over 50 years of combined experience, our founding therapists understand the importance of educating you on the most effective ways to help children attain the essential motor skills to create a strong foundation for their overall brain development.

Therapists Who Care

Not only do we want to share as much knowledge as we can to help families, but we also want to promote professional development of the therapists that learn with us and support them on their career paths. Creating new research and evidence-based therapy, as well as the advancement of the pediatric physical therapy profession is important to us.
