Twig received her Bachelor's degree from Bennington College and a Master's in Child Development from Bank Street College of Education. She has taught young children, developed curriculum and worked as Director of Education for the Center for Marine Conservation in Washington, DC. Mother of two daughters, Katie and Rebecca, she now lives in Cockeysville, Maryland with her family and a small but select group of pets. Fortunately, her husband, David Pittenger, is Director of the National Aquarium in Baltimore. The Aquarium is home to over 5,000 animals so Twig and her girls enjoy the company of many more species than they could fit in their own house.
