About Main Line Play Therapy

Finding the right fit for you and your family is the most important part of the healing relationship. My approach is to see the family system as part of the process which contributes to your child’s overall success. By taking the time to understand underlying behaviors, we can then find creative solutions to these challenges. A child's intensity can be their greatness gift.  

Play therapy & expressive arts therapies offer a safe psychological distance from children's problems where your child can express themselves in a way that is the most developmentally appropriate. It is such a privilege to witness children's play and have them invite me into their world. Creating a healing space for the families I work with is truly the highest honor and I take the work of play very seriously. I have a passion for helping others see  opportunities in their challenges and celebrate successes along the way.

  • Attachment/Adoption

  • Anxiety/OCD

AboutTammi Van Hollander, LCSW, RPT-S:

I am a licensed clinical social worker and Registered Play Therapist Supervisor, and has spent over 20 years working with children, families and individuals. My work and creative interventions in the field of play therapy have been published and internationally recognized. I am  the author of a multi-sensory, attachment-based children’s book titled, Casey’s Greatness Wings: Teaching Mindfulness, Connection, and Courage to Children. The success of the book inspired me to create Casey’s Greatness Sticks & Greatness Cards to be used in schools, counseling and in the home. I specialize in attachment, sand tray play therapy & sensory integration working with infants, children, families, and adults of all ages.

I hold a Master of Social Work from The University of Pennsylvania and have had extensive training and supervision from The Family and Play Therapy Center in Philadelphia.


I am a certified Advanced Trainer for the Nurtured Heart Approach®, a certified FirstPlay® practitioner and a founding board member of The World Association for Sand Therapy Professionals.
