Meet our trainers and coaches
ER Education's experienced consultants bring a wealth of practical and technical knowledge with them when they come to your school. Our backgrounds are as diverse as the organizations we serve, but we all have one thing in common: a passion for helping improve student learning.
Zach Groshell, founder
Zach’s superpower is his obsession with education research and student success — it’s what drove him to found ER Education. Since beginning his career as an elementary teacher, Zach has become an internationally recognized education consultant on the science of learning; author of Just Tell Them, The Power of Explanations and Explicit Teaching; host of the podcast Progressively Incorrect; and an active thinker on education Twitter (@mrzachg).
Zach credits much of his success to his commitment to remaining grounded both in the work that teachers do day to day and in the evidence on what actually helps students learn. He collaborates with teachers and school leaders to connect the two in ways that are practical, motivating, and move the needle on student achievement.
AJ Pettway, consultant
AJ Pettway is an instructional coach and education consultant with over 20 years of experience in international and US public and private schools. He specializes in helping schools strengthen professional learning systems and coaching support by leveraging the science of learning and its practical implications for building teacher expertise. His work focuses on instructional design and delivery, formative assessment, and classroom-level evidence to support teacher growth and improve student learning.
Gene Tavernetti, Ed.D.
Gene has been involved in education for over thirty years. He has served as coach, teacher, counselor, administrator, and consultant. He is the author of Teach FAST and Maximizing the Impact of Coaching Cycles (John Catt Edu) and co-author of Digital Captives, and cofounder of Total Educational Systems Support (TESS).
Gene holds a core belief about children and adults: Given the right environment and proper support, everyone can improve and succeed. This core belief has allowed him to help his students, staffs, teachers, and administrators — with whom he now trains and coaches — to attain the levels of competence they desire.
Christine Teahan
Christine is the founder of CGT Learning Throughline, an independent consultancy through which she coaches teachers and school leaders in explicit instruction and content-area literacy, translating learning science into materials and skills teachers can actually use on Monday morning.
Christine began her career as a special education teacher, where she saw firsthand how much clarity and structure matter for students who can’t afford to be left guessing. She strives to keep the human element at the center of her work, strengthening the connection between the people in a school and the systems they operate within, while staying current through constant reading and listening on the latest research and conversations in education.
