The staff of two teachers and one administrator/director exceeds Wisconsin state requirements for preschool education.

The Holy Cross church staff become familiar faces to the children through chapel time and ongoing visits during the school year.


Please read a greeting from Holy Cross Preschool's Director, Mrs. Seidemann.

Tammy Seidemann,


Hello! My name is Tammy Seidemann. I have been a 4K teacher for many years, and moved to the position of Administrator/Director at Holy Cross Preschool in 2019.  My family and I have been members of Holy Cross for about 11 years, 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.  We moved from Sheboygan to Germantown in 2009 and have enjoyed many exciting experiences at Holy Cross.  My daughter Katherine is a student at Winona State University, and my son Stephen is a Poolee in the US Marine Corps.  In my spare time I enjoy spending time with family and friends, reading and being outside.

Patricia Hendrickson,


Hello! My name is Tricia Hendrickson.  This will be my 3rd year with Holy Cross Preschool, and my 12th year teaching preschool.  I was born and raised in Garland, Texas. My husband is from Wisconsin, and returned here in 2019 for a job opportunity. I have 1 son, Patrick (25). My oldest son, Andrew, passed away in March 2020. 


I graduated from Amber University with a degree in Human Relations/Business, and am 3 hours away from my EC-4 Elementary Education teaching certification from Texas A&M University - Commerce.  Working with children is my passion.  I truly believe God has led me to Holy Cross Preschool, as I have seen His hand in the entire process. I feel honored and blessed to be teaching with such great people and serving such precious families. 

Brittney Rasmussen,


Hello! My name is Brittney Rasmussen.  I graduated from UW-La Crosse with an Early Childhood/ Elementary degree in 2010.  Before coming to Holy Cross in 2016, I taught in childcare with children ages 6 weeks to 5 years old.  I grew up in the area and live here now with my husband, Adam, and son, Landon.  My husband and I are both long-time members of Holy Cross Lutheran Church.  We are even standing next to each other in our confirmation picture!  We enjoy being outside, watching the Packers and Brewers, and going to the zoo.  It is such a blessing to teach here in such an amazing preschool!
