...Alongside colleagues, we created the Child & Adult Advocacy Studies certificate and training programs to prepare service providers and teachers in South Dakota to use trauma informed, multidisciplinary approaches...I honestly would not have pursued this line of service and scholarship had it not been for the conference and hearing Dr. Costa speak. Thank you for sharing your knowledge and your passion for helping children and families heal.

...Gerry is an authentic human being who is able to capture and encourage expansive ideas, hold the space for complex problem solving, and use humor appropriately to soften a message where needed. This is the mark of a  consumate professional, a wise leader who knows how to bring out the inherent wisdom in others. His passion for whatever he is involved in is infectious and I am so grateful for his guidance and leadership in the field, as well as being able to call him “friend”! What a treasure!
