Our People

We are a diverse team of researchers, educators, and passionate professionals.

We are a diverse team of researchers, educators, and passionate professionals who have one thing in common — we share the conviction that all children deserve the highest quality education. That’s why, here at HighScope, we spend our days focusing on the variables that allow all children to be their best selves. Each team member brings a unique expertise to supporting and advancing the field of early education.

And together, we are committed to empowering educators and programs with classroom solutions that allow young children to thrive.


For more than 25 years, Dr. Cheryl Polk has promoted healthy child development, especially for children at risk of school failure and their families.
