Sean Will earned a Ph.D. from Florida Tech while studying volunteer training procedures for animal shelters, teaching social behaviors to dogs, and increasing the adoptability of dogs in shelters. This research led to a dissertation on teaching volunteers how to train social behaviors to dogs in shelters to increase their chances of adoption. While earning an M.S. at the University of North Texas, Sean spearheaded the development of Constructional Affection under the instruction of Dr. Rosales-Ruiz, a training procedure that uses affection in the form of petting and gentle stroking as a reinforcer to teach social behaviors to dogs, and developed constructional shelter programs to increase efficiency in animal shelters. While in graduate school, Sean was a certified educator in Texas, educating youth as a public school special-needs teacher. This unique background provides the foundation for effectively teaching animals and the humans caring for them.
