Preschool & Pre-Kindergarten

Come Grow with Us! The OMPH Preschool (age 3) and Pre-Kindergarten Programs are offered to children who are 3 and 4 years old by September 1. The programs provide activities which are developmentally appropriate in a Catholic environment. Planned indoor and outdoor activities promote physical, social and spiritual growth. Preschool and Pre-Kindergarten programs are held Monday through Friday from 8:00am - 2:45pm. An on-site after school program is available until 5:30pm. Preschool 3 and Pre-Kindergarten students must be potty trained in order to be accepted into the Preschool programs.

Mrs. Adrienne Edmiston, Pre-Kindergarten Teacher

Hello! My name is Adrienne Edmiston and I am so thrilled to be part of the OMPH School team!

I graduated from Indiana University of Pennsylvania with a Bachelor of Science Degree. After a few years of working in the business world, I knew that it was not my true calling. I returned to Shippensburg University and obtained my Masters in Early Childhood Education. I have been teaching preschool for over 10 years with Head Start in Harrisburg and I truly love educating young children!

My family and I have been members of the OMPH Church for many years. As lifelong Catholics, my husband and I knew it was our goal to raise our two daughters and son in the Catholic faith. Currently, our daughters participate in the Religious Education classes at OMPH. I look forward to the opportunity to educate the youngest members of OMPH School and help them to grow both academically and spiritually.
