Assistant Professor

Dr. Justin P. Allen grew up living in the small farming community of McCune, KS and the larger metropolitan area of Shreveport, LA. After graduating from Southeast High School in Cherokee KS, he attended Kansas State University where he earned a Bachelor of Arts in Psychology. While completing his course work towards a Masters of Arts in Psychology (2008) at Washburn University, Dr. Allen began developing an interest in school-based psychological services.

In 2016 Dr. Allen completed his doctoral work in School Psychology at the University of Kansas (KU). While at KU, he worked with Drs. Daryl Mellard and Don Deshler in investigating middle school practices in implementing school-wide academic assessment and intervention methods at the Center for Research on Learning (CRL). While completing his doctoral studies, Dr. Allen worked as an applied Ed.S.-level school psychologist for the Unified School District (USD) 453 in Leavenworth, KS. During his employment at USD 453 Dr. Allen worked in elementary, intermediate, and high-school settings, and also served as the district’s lead school psychologist where responsibilities included providing supervision to students on internship and serving on difficult or disputed psychoeducational cases.

Dr. Allen joined the School Psychology program at Sam Houston State University (SHSU) in the fall of 2017. He teaches undergraduate courses in general psychology, social, and personality psychology, as well as graduate courses in statistics, academic assessment, behavioral consultation, and advanced school psychology. His field-based experiences at USD 453 drive his current research interests in behavioral interventions and team-based decision-making within manifestation determination reviews. He maintains active research collaborations across a number of different universities.

Dr. Allen enjoys spending time with his family, traveling, studying cultures and languages, as well as trail/road cycling.
