Linda DeRosett, Education & Community Outreach Director

Ms. Linda DeRosett started her career in experiential education many years ago at the Orlando Science Center where she created programs for children and adults, all designed to enhance a sense of wonder about science of all kinds. She then went to work for the Walt Disney Company where she also created education programs in art, science and history. She was on the opening team for Disney's Animal Kingdom, and became a Curator of Education where her job was focused on helping guests better understand how their actions affect the natural world and wildlife. She returned to her hometown of Lexington to be near family, and is mom to an amazing 16 year old daughter.
