Meet Principal Carly Hertel

Carly HertelCarly Hertel earned her Bachelor’s in Education with minors in Early Childhood Education and English as a Second Language at St. Norbert College in DePere, Wis.  She earned a Master’s in Educational Leadership from Concordia University-Wisconsin (CUW) in 2016 to obtain her principal licensure and director of curriculum licensure. Carly taught grades K4, K5, 4th, and 5th grade in the Green Bay Area Public Schools and served as the English as a second language teacher for the district. In this role, she supported students and families who were new to the country through a refugee placement program. Carly worked as a Multilinguistic Instructional Coach for teachers and principals at three dual-language schools for the School District of Waukesha. If you ask Carly, she’ll tell you that God led her to LUMIN Schools and St. Martini. She had prayed about becoming a principal but also highly valued dual language instruction. When she heard about the opening of St. Martini from a family member, she knew it was an answer to prayer and the best of both worlds. She has served as principal of St. Martini since 2018.

What makes St. Martini Lutheran special?

“What makes St. Martini special is our family feel and atmosphere. It really feels like one big family and we are always here to pick each other up and celebrate one another. I believe that makes our community extremely special and unique! I have worked for a lot of schools prior to St. Martini and I have never experienced anything quite like it!”


What is your philosophy about education and its importance? 

“Education is the cornerstone of having a more just and equity-driven world. I believe that through education you learn to challenge, question, persevere, love, and be curious! My hope is that all of our scholars are able to reach their full potential and can continue to have a family, community, and global positive and christ-centered impact!”

What do you love about what you do?

“I love that I am able to serve others every day. The St. Martini family and community is a beautiful place and I am so grateful to be a part of it! I love watching scholars grow academically, socially, and in their relationship with Christ. What is there not to love?!”

What is your hope for LUMIN scholars as they grow? 

“My hope for LUMIN scholars is for them to grow in their identity as a child of God and to fulfill their purpose that God has so carefully designed for each of them! There is so much power in knowing and celebrating who you are and knowing that you are the son or daughter of our King. My hope for all our scholars is that they embrace this. Your voice and your identity are powerful and important.” 

Favorite bible verse? 

“Whoever pursues righteousness and love finds life, prosperity, and honor.” - Proverbs 21:21

What is your greatest accomplishment? 

“I believe that my greatest accomplishment is working in a place where I feel like I am serving within my God-given purpose. I feel so blessed to serve the St. Martini Community and I truly enjoy coming to work every day. This to me feels like a great accomplishment as I get to work alongside amazing people and children every day.”
