At Cornerstone We Believe That Therapy Should Be a Positive and Fun Experience!



Our goal is to provide our families with :






We've seen your dilemma: you've just been told your child needs therapy and you don't know where to turn. Whether your child has a short term problem or a more complex issue you could be experiencing feelings of confusion, overwhelm, fear, and grief. You may have numerous questions and concerns regarding what is the best possible treatment for your child. Your overwhelm at the diagnosis of your child's problems is not new to us.

We've held many parents' hands like this; we've hugged many kids like this, and we've seen the changes in both the parents and the children after we started intervention.

We build a foundation for your children so that they can learn to live, cope with their challenges, reach their fullest potentials, and succeed. We change parental fear to hope through scientifically based methods, education, evidence based practice, and interventions. Hope does exist at Cornerstone Therapies.


We believe that therapy needs to be individually tailored and continually modified in order to meet the child's needs. We believe the parents are an integral part of the team and welcome their input and participation in their child's journey.

Our knowledgeable and caring staffs' number one goal is to serve children with special needs. Care is the Cornerstone of our practice.
