CRG’s Speaker’s Bureau
CRG’s Speaker’s Bureau helps schools, colleges, community agencies and other organizations learn more about children, teens, and adults with disabilities and/or behavioral health issues such as depression and anxiety. Most of our providers are available to give talks and/or conduct trainings on a wide range of topics. We work with you to customize a presentation that combines research-based knowledge with practical strategies and applications. As you plan your group’s professional development events for the year ahead, we invite you to contact Angela Middleton at (317) 575-9111 ext 140 to discuss your needs.
