When she isn’t working, Danielle spends her time with her son, Jack, and their dog, Lucy. Danielle enjoys being an active participant in the community, and volunteers in many ways to provide meaningful inclusion opportunities for children. Danielle grew up playing sports year-round, and she now coaches Jack’s soccer, basketball, and baseball teams, too.
