Meet Dr. Dehn

Dr. Milton J. Dehn earned his BA in Psychology from the University of Minnesota, his MS in School Psychology from Moorhead State University, and his doctorate in Educational Psychology from the University of South Dakota (1992). He has practiced as a school psychologist in four Midwestern states and is currently a private practice school psychologist in Wisconsin. Dr. Dehn taught for 13 years in the School Psychology Program at the University of Wisconsin-La Crosse, where he also served as program director.

His interest in assessment of psychological processes began with his dissertation research. He later developed a selective, cross-battery model for psychological processing assessment, which is described in his 2006 book—Essentials of Processing Assessment. That publication was followed by Working Memory and Academic Learning: Assessment and Intervention, Long-Term Memory Problems in Children and Adolescents: Assessment, Intervention, and Effective Instruction, and Helping Students Remember: Exercises and Strategies to Strengthen Memory.

In 2003, Dr. Dehn co-founded Schoolhouse Educational Services and Schoolhouse Tutoring®. At Schoolhouse Tutoring® in La Crosse, Wisconsin he continues to conduct psychoeducational assessments, consult with parents, and provide memory training and interventions to students with memory problems. Dr. Dehn is a frequently requested speaker and has conducted 100+ state, national, and international presentations or workshops on processing assessment, working memory, and interventions for students with long-term memory impairments.
