Our trained teachers are dedicated to providing quality education to all the students of our school. We rejoice in the opportunity God has provided to us to grow our family and His through our participation in the Racine Parental Choice program since 2012. Together our administrator, faculty and support staff is eager to respond to God’s mission. Take a look at the staff in Concordia Lutheran School in Sturtevant, WI.

  • Mrs. Jeannine Klein, Principal

    Concordia Lutheran School exists for the purpose of "Bringing Christ and academic excellence to our students for life and forever." The school will celebrate its 50th anniversary in January of 2010. We give thanks that He has blessed our mission and ministry each of these years. I am privileges to have been part of the ministry at Concordia since 1986, coming as a graduate of Concordia, Mequon to teach second grade initially. 

    My interest in pursuing a career in the teaching ministry was encouraged and developed by outstanding educators I encountered in my experience in a Lutheran elementary school. Later, a desire to pursue administrative coursework was furthered by family, friends, colleagues, and the work of the Holy Spirit. In 2002, I completed the School Leadership Development Project, receiving certification for principalship in the Lutheran Church Missouri Synod. In 2004, I accepted the position of principal and at that time also served as part-time third grade teacher.

    It is an incredible blessing to work with a very talented, caring group of servants who are committed to bringing students into a closer relationship with their Lord and each other. At Concordia, the students, teachers, and parents work together as a team, both in and out of the classroom. The sense of family and dedicated service that I have been a part of, and which anchors me at Concordia, is one that encourages a love for learning and life-long service. It is my prayer that just as my life was touched by educators committed to preparing God's people, that the staff and I together inspire our students to service in His kingdom.

    Teaching Information: Concordia Lutheran School extended a Call to me to serve as the second grade teacher in 1986, as a graduate of Concordia University Wisconsin. The Lord led from one Concordia to another and this has been my home ever since. Many of my 28 years teaching were spent in second grade or third grade, but I have also enjoyed teaching fourth grade, and third and fourth grades combined. At the conclusion of the 2013-14 school year, I moved from the classroom to full time administration.   

    I have three children, Brenden (Concordia Lutheran School graduate - Class of 2003), Kellen (Concordia Lutheran School graduate - Class of 2007) and Shaylyn (Concordia Lutheran School graduate - Class of 2009). Seeing their faith and friendships grow at Concordia was truly one of life's greatest pleasures. Their time at Concordia most definitely helped shape their future and develop the character and work ethic that they possess as adults. (Yes, I am a proud mom – but recognize that their teachers were significant in contributing to the successes they enjoy today.)

    My husband Norman and I enjoy country music, as well as supporting our Milwaukee Brewers, Wisconsin Badgers and Green Packers.

  • Ms. Karli Luchterhand, Assistant Principal
    My history with Concordia has been a long one. It started when I was just three years old and my dad took a call to be pastor at Holy Cross Lutheran Church. I attended Concordia starting in kindergarten (they didn't have a preschool program back then) and was fortunate enough to have Jeannine as my third and fourth grade teacher. I graduated from Racine Lutheran High School and went on to attend the University of Wisconsin – Platteville, majoring in Elementary Education with a minor in Early Childhood.

    During my time at Platteville, God blessed me with many opportunities to work in the classroom at Highland Elementary School. I ended up student teaching at Concordia in the fourth grade class under the direction of Mrs. Kosmala. Immediately after graduating in 2006, I took at long term substitute position at Concordia in the 7th grade classroom teaching literature and technology to the upper grades. The following fall, I long term subbed in the fifth grade classroom teaching math to the middle schoolers.

    Shortly following my time at Concordia, I took a position at Shepherds College as an academic advisor and instructor. Shepherds College is a post-secondary school for young adults with disabilities. As an academic advisor, I had 8-10 students on my caseload. Because students come from all over the world, they reside at the school, which means that as an advisor, I was responsible for everything from finance to hygiene to behaviors. For my five years at Shepherds, I taught a myriad of classes including math, language arts, study skills, communications, life finance, and trained for life. I believe that each student is created by God on and for a purpose with specific gifts and abilities. This means that each student is either a visual, auditory, written, or kinesthetic learner. I try to have each of those learning styles in the lessons I teach in order to maximize the amount of information a student retains.

    I bring all of the knowledge and passion I have for teaching to Concordia. I'm very excited to be at a school where the staff focuses on bringing the Gospel and the love of God to each student. I am proud to be a part of this fantastic team of teachers.

    Now for a little about me personally - I enjoy playing the piano, leading worship/directing choir, reading books by Torey Hayden, and cheering for the Packers with my family.

  • Mrs. Susan Ritacco, Preschool Aide

    I was born and grew up in northern Minnesota. I enjoyed snowmobiling and the many lakes. I have a very large extended family and love getting together with them for parties and camping. I worked many jobs before moving to Racine in 1979 with my 3 children. Some of those jobs were supervising outdoor skating rinks, church custodian, factory work, cooking in a drive-in, and teaching at Head Start where I earned my Early Childhood Certificate from Bemidji Sate College.

    I worked for Racine Unified Schools for 28 ½ years in secretarial positions before retiring. I have raised 3 children plus 3 grandchildren (Turner is the youngest).

    I say God's plan for me is to be involved with children since I've been raising children for 50 years!

  • Mrs. Korie Baganz- Pre-Kindergarten 4 Year Old Teacher

    Since graduating from Concordia Chicago with a bachelor’s degree in Elementary Education and a minor in Art, God has blessed me with several Calls that have provided many different opportunities to serve Him while growing as an educator and continually growing in Faith over the last fifteen years. My first Call was to Trinity Lutheran School in Mequon where I taught 3rd Grade for two years. After that, I accepted a Call to a school that holds a very dear place in my heart: Concordia Lutheran School! I taught both 3rd Grade and Kindergarten here at Concordia for four years from 2006-2010. God then Called me to become the director and preschool teacher at Prince of Peace Early Childhood Center for six years from 2010-2016. God then answered my prayers and a strong desire in my heart to again be in the classroom fulltime where I could spend more time with students, more time shaping minds and teaching about Jesus. He directed me back to Concordia Lutheran School! I was absolutely thrilled!

    God has also placed one other special Call on my heart: the Call of adoption! After a long journey, in August of 2015, my amazing son was brought home from China. I happily share this story because adoption showed me God’s Hand in this world like never before and I am eternally grateful for the way God shaped my heart during this remarkable journey. Abel, is absolutely my greatest joy!

    Some of my other passions include reading, spending time outdoors, and I love to visit my parents who live in Minocqua, Wisconsin and get out on the lake! Spending time with my family is my favorite activity.

    Christian education has been a part of my life since preschool and I am so thankful for it! I look forward to all the good things God has planned for all the children, families, and staff each and every school year.

  • Mrs. Julie Arndt, 5th Grade Teacher

    My name is Julie Arndt. I graduated from Martin Luther College with a Bachelor’s Degree in elementary education. This is my 15th year of teaching, eleven of which were here at Concordia.

  • Miss Kati Luchterhand, 5th Grade Aide

    Growing up, my dad was a pastor at Holy Cross and so I attended Concordia until I was in fourth grade. Knowing Christ and understanding Scripture have been a valuable and intricate part of who I am since I was very young. Concordia's purpose in "Bringing Christ and academic excellence to our students for life and forever" is a vision that resonates with me. The Gospel message is one that is not focused simply on life after death; it is a message of hope and life for the present. It is a message that offers grace to every person in any circumstance.

    Just prior to starting my current job here at Concordia, I spent six months in Senegal, West Africa with a missionary couple as they began their first oversees mission assignment. I was the live in nanny for their two children while they took French lessons and began to acclimate to life in a new culture. This experience gave me a deeper understanding of myself and my priorities in life. It clarified my perspective and the values that I wish to maintain and instill in those around me. Values such as striving for a heart of compassion that reflects the heart of Christ; nurturing a sense of curiosity and creativity; learning to respond with courtesy and respect, especially when human nature defies such a response; and developing the ability to communicate thoughts and emotions with clarity.

    As I begin my third year of working at Concordia, I pray that I would be able to "Preach Christ always and, if necessary, use words" (Francis of Assisi).

  • Mrs. Sandra Thibodeau, 6th Grade Teacher
    My name is Sandra Thibodeau, and I am excited to be a part of the ministry here at Concordia Lutheran School! I am a Wisconsin native, born and raised in Portage. After many years away, I find myself back in my home state.

    I traveled extensively as a U.S. Air Force spouse before attending Concordia University - Nebraska. I graduated with a Bachelor’s degree in elementary education, and a concentration in English, as well as a Lutheran Teaching Diploma.

    I have served the Lord these past 14 years at schools in Lafayette, IN, Austin, TX, and most recently, Menomonee Falls.

    I have two adult children - Alexander and Nicole. I enjoy cooking/baking, knitting, reading and being outdoors. I also enjoy spending quiet time at home with my two cats.

    I consider it a blessing and a privilege to be able to minister to students, families and co-workers through my position as a teacher. My prayer is for all children to recognize that they are “fearfully and wonderfully made” by our Creator
  • Mr. Christopher Drager, 7th Grade Teacher

    My wife, Dena and I are blessed to have two grown children one of which is an alumna of Concordia.

I look forward to equipping your children with useful knowledge, math skills, tech skills, and a love for Christ that allow your children to be successful in high school and productive members of our community.
