CT3 is one of the leading providers of professional development for education and school culture planning in the United States, serving schools across the country.

CT3 co-founder, Dr. Kristyn Klei Borrero, created the No-Nonsense Nurturer approach and Real Time Teacher Coaching through a collaboration with Lee Canter. She consults with school district leaders and changemakers in the field of education to better teacher practice and boost student engagement. CT3’s work has influenced best practices in turnaround education and increases educational access for underserved students.

Kristyn leads a diverse team of CT3 associates who share her passion for educational equity. Throughout the school year, they bring practical experience to educators and train coaches to increase in-classroom teacher support. They work with school leaders to build healthy school cultures that confront bias, raise expectations, and break down barriers. CT3 associates often write for national publications and present at conferences.
