"Assistant Caregiver for a Day" Program. During your visit you will have the opportunity to experience life as a caregiver by joining our staff and assisting with daily care of our 40 gibbons. Your day will start by learning about the Gibbon Center and our mission. We will go over safety training, preparing food, carrying buckets, learning about the individual gibbon and family dynamics, and at the staff members discretion, tossing food to the gibbons.
