Parent and Child Therapy

Using behavioral therapy to help strengthen the parent and child relationship by increasing healthy attachment and communication. Behavior therapy for young children is most effective when their parents learn strategies from therapists and use those strategies to manage their children’s behavior. Parents learn to create structure, reinforce good behavior, discourage negative behaviors, provide consistent discipline, and strengthen the relationship with their child through positive communication.

"Sand tray therapy allows a person to construct his or her own microcosm using miniature toys and colored sand. The scene created acts as a reflection of the person’s own life and allows him or her the opportunity to resolve conflicts, remove obstacles, and gain acceptance of self. Through creative expression, a person in therapy is able to manifest in sand the things they would otherwise not be able to vocalize or address in traditional therapy. The therapist treats the person as whole and healed, knowing that the process of sand tray therapy allows the person to find the answers that are already within them". - GoodTherapy
