Hello!

My name is Mrs. Heather Sickinger. This is my 23rd year in Education and my 22nd year in the Archdiocese of Philadelphia. I have taught here at St. Mary Catholic School for 19 years. I love teaching and everything SMS especially getting to help mold the children here at St. Mary’s into tomorrow’s leaders. It is my absolute pleasure to have been named Principal and look forward to helping our school community be the best it can be.

I was born and raised in Philadelphia, Pennsylvania. I moved to the Royersford area in 2003. My husband, Ray, is an engineer in Collegeville and I have two children. Rayme attended SMS from Pre-K till he graduated 2022. Kimmy attends St. Mary's and is in the 7th grade.

I graduated from Cabrini College in 2000 with a bachelor's degree in Early Childhood and Elementary Education. I look forward to many more years of leading and teaching the students at St. Mary School.
