Biography


Growing up as a struggling student with Attention-Deficit Hyperactivity Disorder and a learning disability, Gary E. Schaffer, PhD, has dedicated his professional life to helping all learners succeed. After earning his bachelor’s degree in special education and English, Gary went on to obtain a PhD in school psychology and become both a school psychologist and a clinical mental health counselor. Before obtaining his PhD, Gary practiced as a school psychologist in school, hospital, and state agency settings for over a decade, primarily working with diverse learners and individuals with developmental disabilities.

Currently, Gary is a full-time Assistant Professor at Niagara University, where he teaches graduate students in school psychology and counseling. He is also employed as a school psychologist at Gateway-Longview, an alternative school for children with social-emotional differences. He has authored numerous scholarly articles, books, book chapters, and programs on topics such as MTSS, autism, disability advocacy, and school psychology leadership, and he has consulted and presented nationally on these subjects. His two most recent books, published by SAGE and Routledge, are Multi-Tiered Systems of Support: A Practical Guide to Preventive Practice and Implementing Universal Social-Emotional Programs: A Step-by-Step Guide for Schools. His upcoming text is entitled MTSS for all: Building truly inclusive systems for students with disabilities. Routledge. Nationally, he offers consultation and presentations on Multi-Tiered Systems of Support and provides insight into best practices in prevention under three-tiered frameworks, such as RTI and SWPBS.
