As critical race theorists would remind us, those most impacted have the greatest insight to create change. This paper applies a critical race theory framework to explore the leadership experiences of two African American and one Latinx American mathematics teacher educator and how they address issues of race, racism, and (in)justice in teacher professional development. Data analysis from semi-structured interviews, publicly available webinars and podcasts, and other published materials from the educators (eg. articles and books) reveal how they engaged teachers to attend to issues of race and racism by challenging persistent masternarratives about mathematics and mathematics ability; centering on counternarratives on the cultural identities and mathematical understanding of students of Color, and engaging in community-based pedagogies to promote coalitional resistance.
