Judy Leimbach received her master's degree in Instructional Strategies in Gifted Education from National-Louis University. She has 14 years of experience teaching in regular classrooms, kindergarten through fifth grade, and 14 years experience teaching gifted students in grades 1-5. In addition, she has spent 5 years supervising groups of student teachers at Wheaton College. When she first started teaching in a gifted program, there were few materials available for gifted students in primary grades, so Leimbach began writing her own and had several books published. Having previously taught in the regular classroom, she also was very aware of the need for high quality, easy-to-use materials for regular classroom teachers to use for their gifted students in both primary and intermediate grades. She began working with other teachers, including her daughter, a middle school math teacher, to develop materials to meet that need. Kathy Leimbach received a degree in Math Education from Valparaiso University and a master's degree in Education from National-Louis University. She taught math at Glen Crest Middle School in Glen Ellyn, IL for 34 years. She retired in June 2015.
