During therapy sessions, Tiffany utilizes art and play to work toward a shared understanding of the child’s perspective. With the recognition of the child’s emotions, in relationship to their experiences, she encourages a deepening of the child’s self-awareness by providing children with an open space to recognize their own perspectives and intentions when they relate to the world around them. Throughout the therapeutic process she assists children to develop a healthy and resilient perspective focused on the child’s strengths. This allows for a life lived more freely and responsibly.

Tiffany works with families and children with diverse backgrounds.
