But what ELSE makes IAST different? 


IAST is a non-profit organization

IAST is a non-profit organization that exists solely to promote sandtray therapy across the globe. IAST consists of a 5-member board and various other committees to ensure that it is adhering to it’s original mission statement.


IAST is the credentialing body for sandtray therapists

The IAST acts as the credentialing body for those wishing to earn a sandtray credential. 


AST is completely member – driven

Think of IAST as the David against the Goliath of other mental health organizations. We strive to keep our overhead and bureaucratic tape to a minimum so we can stay streamlined, agile, and able to shift to the needs of our members and the current mental health trends.


We are an international organization

We recognize that therapists operate around the globe with the healing power of sandtray work. We do not want the therapist’s place of birth to hamper them from participating in sandtray trainings.


 The board of AST 

The board of IAST continually evaluates the criteria for a sandtray credential and those trainings that lead to the sandtray credential. We strive to stay at the top of the sandtray trainings while making the credential available to those who wish to obtain it (we do not want to be too exclusive that it becomes an inner circle but do want to maintain the quality of the sandtray credential.)
