Cornerstone Teachers

Cornerstone teachers are passionate early childhood educators. Ongoing professional development allows our certified, caring educators bring innovative and developmentally appropriate methods of instruction to their class every day. Our teachers are committed to creating an environment that promotes the development of the whole child. All staff are First Aid/CPR certified.

“The teachers are really doing a lot to make sure that there’s an experience for each kid. I was really impressed with what I learned at back-to-school night. Our particular teacher would discuss strategies for the children’s learning and development. And, I feel that the teachers really want to be there. They’re present, they care a lot and they’re passionate about education.”

Assistant Teachers

Assistant teachers are a vital part of the Cornerstone learning community. Often the first in the building and last to leave as several staff our before and after care programs. They provide assistance to our lead teacher that goes well beyond an extra set of hands in the classroom. They get to know our students and their families well. They are required to implement our curriculum and discipline policy as effectively as the Lead Teachers they work beside, forming a cohesive teaching team.

Our assistant teachers come from a variety of backgrounds. All are college graduates or currently students in fields related to early childhood. Several have advanced degrees in other fields and are exploring a move to the field of education. Their continuing education requirements are the same as our lead teachers.
