On July 4th, 2011, Developmental Services Ontario Eastern Region will open its doors to the public and officially begin as the central point of access for adults with developmental disabilities in the Eastern Region. Throughout the years we will continue to strive to provide a good service to you. To help us do this we would like to hear from you so, Developmental Services Ontario Eastern Region plans to expand its website to add a section for customer feedback. It will also develop a Question & Answer corner and add a  photo gallery of events and storytelling.
