Dedicated Staff

Fr. Cletus Basekela, Pastor

Mrs. Anne McNeill Gattman – Principal

Welcome to St. Jerome School! It is a very wonderful place for children and families. I am our new principal. I have been a teacher, curriculum leader and assistant administrator throughout my career. I have a Masters from the University of St. Thomas and my K-12 Principal License from the state of Minnesota.  St. Jerome School has a caring heart and arms wide open. We believe Catholic education is a blessing and advantage, and we want as many children to have that opportunity as possible.

I am a mom to three sons and Jim is my husband. Our whole family looks forward to our years ahead as part of this awesome school community.

Mrs. Shelly Berthiaume – Grade 2

This is my 12th year teaching at St. Jerome. I always knew I wanted to be a Catholic school teacher, so I studied elementary education and Catholic Studies at the University of St. Thomas. I also received my masters degree in special education from UST. I have been very blessed to be a part of the St. Jerome community for all these years. The school is very close and students can soar to unimaginable heights!

I have been at St. Jerome for 20 years or so. Obviously I love working here. I am impressed with the dedication of Mrs. Sherman and the staff. But I most appreciate the investment that parents have made in their children. The students achieve at a higher rate when we all work together.
