In Memoriam

It is with a heavy heart that we announce our beloved friend and colleague, Pukadog, has passed away.  She retired 2.5 years ago after working with children at our office for 12 years.  Pukadog was known for putting children at ease for testing, stealing snacks, and her sense of humor.  She had a big and full dog’s life. She passed quietly in her favorite spot with people she loved and a belly full of Indian food.  Pukadog will be missed.
