    Praise for Rachel

    "Rachel Heller brings a wealth of experience to the table. She was particularly adept at facilitating discussion, which was especially impressive given that a wide variety of subject areas were represented.  I know that I am not alone in saying that I will be going back to my school with a wealth of ideas.." - Brad Masoni, American International School of Rotterdam
