Tracy Gallagher

Communications Director and Events Coordinator
Tracy Gallagher is passionate about K-12 education and helping teachers become better at their craft. She began her education career at Anova working in special education classrooms and for the last six years in publishing, partnering with thought leaders like Doug Lemov, Michael Fullan, and Daniel Willingham to create useful and inspiring professional development books for teachers and administrators. While at Wiley Publishing she helped manage and grow the Teach Like a Champion brand, solidifying her interest in teacher retention and effectiveness.

Teaching can be a solitary profession and many new teachers don’t feel adequately supported or trained. By coming together, teachers and administrators tap into their most valuable resource, each other.
