An important statement from OCTM

As educators, one of our most important roles is helping others see perspectives beyond their own. Racism has impacted the lives of African Americans and Black people in our country for over 400 years. They continue to suffer, along with people of color and other marginalized people in our country as their voices and lives are oppressed by those with privilege. Staying silent in our society when injustice occurs promotes continued oppression. OCTM is committed to actively supporting, including, and engaging educators representing all of the diversity in our communities. We see you; we need you, and we are better with you. We assume responsibility for working to welcome and elevate all and to allow your important voices to be heard. We must work together to create a future for our children where no voices are silenced and where all lives are equally cherished and valued.
