Tammi is a skilled and knowledgeable presenter. Her sandtray therapy workshops are interactive, experiential and well received by attendees. I have the highest professional respect for her work in the field of play therapy.

Dear Tammi


Thank you so much for the wonderful play therapy workshop you facilitated at the Jaffa Institute, in Israel. You presented in an understandable and simple way, and all the participants felt that they received concrete tools to work with the children in the future. 


It was a real pleasure to be there, watching you light the room with your passion and expertise in the field. Thanks to you, we can now see the educational power of everyday objects that surround us on a daily basis.


The theoretical and practical insights complemented each other perfectly, providing a rounded experience for all involved.


We would be delighted to take part in something similar in the future.

Thank you so much for giving us the opportunity to experience your work first hand.


Our very best wishes,

Liat and  Sarit: The Jaffa Institute, Israel

Tammi is an energizing, infectious speaker who engages her audience with her passion. Leaving her training, you take tools that you can use the next day. I thought I knew a lot about sandtray therapy, but Tammi's training showed me a whole new world! Not only do I heartily recommend her, I want her back!"
~ Anne K. Crothers, M. Ed., Allentown, PA


Several teachers made a point of sharing that they thought the presentation was one of the most practical, well-done, useful in-services they had ever attended, and loved Tammi’s style and ability to laugh with us.”

~ Donna Lindner, Head of Lower School/The Agnes Irwin School



Play/Sandtray therapy has been wonderful for our daughters (and for us). Tammi helps them work through their feelings through play and provides them with valuable tools to express their emotional needs.  Family sandtray sessions have been very effective in helping us understand our children's fears and insecurities and provide insights into our family dynamics."
~ Lauren (mother of 7 and 3 yr old)
