Hello! My name is Tammy Seidemann. After teaching 4K for many years, I moved to the position of Administrator/Director at Holy Cross Preschool in 2019 and assumed the Head of School position when we began our expansion efforts in 2024.  My family and I have been members of Holy Cross since 2010, but our family has a long history here.  My husband’s grandparents were members for a very long time, and my in-laws were married here over 50 years ago. In my spare time I enjoy kayaking, bike riding, sewing and listening to audio books. I am so blessed to be part of the staff at Holy Cross.

Hello! My name is Katherine Seidemann. I graduated from Winona State University with a cell and molecular biology degree in 2022. This is my first year teaching and I am excited to get started. I have been a member at Holy Cross since childhood. I am originally from the area and I am glad to be back. In my spare time I enjoy reading, quilting, and spending time with my friends and family. 

Hello!  My name is Brittney Rasmussen. Ever since I was a child, I knew I wanted to be a teacher.  I graduated from UW- La Crosse with an Early Childhood/Elementary degree.  I have been teaching 3K here at Holy Cross Preschool since 2016.  Before coming to teach at Holy Cross Preschool, I spent almost six years working with children ages six weeks through five years old.  My husband and I both grew up as members of Holy Cross Lutheran Church, and I am blessed to now be a teacher here!  In my spare time I enjoy spending time with my family, watching sports, doing puzzles, and reading a good book.
