Supporting Positive Behaviors through Executive Function and Developmentally Appropriate Guidance. 

Effective behavior and classroom management begins with understanding how to foster executive functioning in children. Skills such as adaptable thinking, planning, self-monitoring, self-control, working memory, time management, and organization are all foundational for student success—and they can be intentionally nurtured through daily routines and developmentally appropriate practices.
Stephanie Lester, founder of S.L. Lester Educational Consulting, LLC, brings over 40 years of experience in education, including roles as a classroom teacher, middle school principal, Early Childhood Special Education Director, and Director of Curriculum, Instruction & Assessment. As an educational consultant, she partners with schools to deliver evidence-based professional development and coaching cycles focused on behavior guidance, executive functioning, and classroom management that supports the whole child.
Stephanie’s approach emphasizes the intentional embedding of guidance strategies into daily instruction to promote positive behavior, build self-regulation, and increase student engagement. Her training explores how cognitive processes—working memory, cognitive flexibility, and inhibitory control—can be developed through classroom routines, transitions, and interactions.

Having served as a key member of a district leadership team that launched Positive Behavior Interventions and Supports (PBIS), Stephanie has experience creating individualized behavior plans and designing districtwide guidance systems. Her work spans early childhood through secondary education and includes training educators on proactive strategies, relationship-building, and responsive classroom practices.
In addition to consulting, Stephanie teaches these principles weekly as a college professor, combining current research with real-world applications. Whether working one-on-one with educators or facilitating system-wide initiatives, she equips schools with tools and strategies to cultivate calm, respectful, and productive learning environments.
