We will contact any insurance and many times a special agreement can be made with your insurance provider to cover all or part of the cost.  Other payment options can be considered also to work with your particular situation.

Why Sand Castle


 Sand Castle Counseling is a very specialized service, primarily treating children as young as two years through early adulthood. Sand Castle Counseling uses primarily a play therapy model in working with children, adolescents and families. 

Children's behavior can signal problems in the family. The entire family may become distressed because the child's problems are so disruptive. Children and families heal faster when they work together. 

 Sand Castle works in conjunction with Pediatricians, Guidance Counselors, teachers and Psychiatrists in an integrated team model. This extra effort can lead to a more successful result 

Why Play Therapy


Play therapy is used as an intervention of multiple conditions and concerns, such as anger management, grief, loss, family dissolution, trauma and modification of behavioral disorders including anxiety, depression, attention deficit hyperactivity (ADHD), autism or pervasive development, academic and social development, physical and learning disabilities and conduct disorders. Research supports the effectiveness of play therapy with children whose problems are related to life stressors such as divorce, death, relocation, hospitalization, chronic illness, stressful experiences, physical and sexual abuse, domestic violence and natural disasters.
