The birth of Elizabeth's fourth daughter, Caroline, changed her focus towards children with special needs after Caroline's diagnosis of metabolic disease with associated brain injury. Elizabeth testified in Austin before the state legislature to help pass a law allowing persons with brain injuries to get cognitive therapy paid for by insurance.
In 2007 the DeLuca family became foster parents for babies from catholic charities. This has been the most rewarding volunteer work of all. The current focus of Elizabeth's work is Texas Children's Hospital's Vision 2010 campaign, building a state of the art research and diagnostic facility for children with neurological disorders.
Elizabeth is also active in the activities of her three oldest daughters: Lauren, Allison, and Virginia and believes that her children and their interests are her most important job.
