I am Mary Claytor, the lead teacher in the 3 day 3's program. I have been at St. Mark's since the Spring of 2009.

I studied History at Trinity College, University of Dublin in Ireland, where I also hold dual citizenship. I am certified in Early Childhood Development through Anne Arundel Community College. I have taken many seminars and courses over the years including Johns Hopkins Reading Readiness program. 

My husband, Ray, is retired from Engineering with Verizon. I have three grown children whom all have wonderful mates, I would be proud to call my own. Together they have blessed me with 12 beautiful grandchildren.

Besides spending time with my family, I love to read, garden and work on family genealogy. 

My goal for the children is to instill in them a love of learning, to be happy coming to school, to value self-worth and to interact with others in a safe, stimulating environment.
