Meet our Director – Kristin Mantey

Kristin is the director of Cornerstone and is also the lead teacher in Preschool Room #4.  Kristin’s love for her Savior and for children led her to receive a Bachelor’s degree from Martin Luther College in 2007 with a double major in Elementary Education and Early Childhood Education.  Kristin has served as a director and lead teacher at early learning centers in Winston-Salem, NC and Manhattan, KS.

Kristin comes from a large family.  Because her five siblings are spread throughout the United States, travel is one of her favorite things!  Her travels to visit family includes spending time with her 16 nieces and nephews.

Believing that children are a gift from God and that childcare is a partnership between the caregiver and parents, one of Kristin’s joys is supporting families.  She is readily available and eager to share and ideas and information with parents.  She is excited to be at Cornerstone and to partner with your family!

Preschool Room #4 Teacher – Angela

I am new to working in the child care world, but have been working in a school district as a school based mental health professional for the past few years. My goal has always been to work with children and help them in some aspect and I look forward to continuing that goal here at Cornerstone. I received my Master’s in Community Counseling and B.A. in Psychology, both from St. Cloud State University. I am also an alumni of St. Croix Lutheran High School and it was during high school where I became interested in the idea of pursuing a degree in counseling.

I recently got married in August to my husband Paul and we have been enjoying settling into our home, as well as taking care of our two dog fur babies Reese and Rocco. In our spare time we like to do a lot of motor sports activities including four-wheeling, snowmobiling, and motorcycle riding. I also enjoy running, going to different coffee shops, visiting both our families, and spending time at the lake.


Preschool Room #5 Teacher – Renee Sellner

I joined the world of child care in 2004 when I started working with a family that had three children with autism. After working as a PCA for 4 years, I started nannying, and have worked with several families. In 2013 I became an assistant teacher at a small center in River Falls, WI. Since then I have worked at two other centers here in Minnesota, as well as getting my CDA in December of 2016.

One of my favorite things about teaching is seeing a child finally learn or understand something they having been working on, the “ah-ha” moment. I love knowing that I helped them make the connection. Children often enjoy all the silly songs I sing. I find that songs can help engage the class as well as get the sillies out.

I am looking forward to getting to know the children, and meeting all of your families!
