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.

    Concordia Lutheran School exists for the purpose of "Bringing Christ and academic excellence to our students for life and forever." The school celebrated 47 years serving the community and our Lord in 2017 and He continues to bless this mission. I have had the privilege of being 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.

    I have the privilege of working 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 alike work together as a team, both in and out of the classroom. The sense of family and dedicated service that I have found, 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 I, too, along with the staff at Concordia might 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 me there and this Concordia 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 has been one of life's greatest pleasures. Their time at Concordia truly helped shape their future and develop the character and work ethic that they possess as adults. (Yes, I am a proud mom – but also 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. Theresa Mierow, Preschool 3 Year Old Teacher

    I began working with preschool students as an aide during the 1993-1994 school year. I enrolled in early childhood classes and received my certificate as a preschool teacher. I began teaching in January of 1994 at which time I enrolled in classes and received my certificate as a Program Director.

    My husband Gordie and I have been married for 31 years. We love to camp and we spend most of our summer at our camping resort in Plymouth. I also enjoy painting ceramics and teaching country line dancing two nights a week. This is something I have been active in doing for more than twenty five years. I also spend my free time visiting shutins in nursing homes and assisted living facilities and shooting darts.

    We have lived in Racine for 31 years. We are members of Living Hope Lutheran Church where I enjoy being a part of their puppet ministry and have on occasions helped serve dinners at HALO. We also support the Samaritan Purse Christmas Child Program every year through our church.

    We have five children (four sons and one daughter) and ten grandchildren. My oldest son James and family live in Oshkosh. Our son Curt and family (2 children) live in Racine. Our son Clint and family (3 children) in Las Vegas, NV and our son Craig and family (1 child) live in Racine. Our daughter, Becky and granddaughter and grandson live in Racine.

  • Ms. 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 serve Him while growing as an educator and continually growing in Faith over the last thirteen 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 as well as my husband’s: Three years ago God wonderfully placed the Call of adoption on our hearts! After a long journey, in August of 2015, we brought home our amazing son from China. We happily share our story because adoption showed us God’s Hand in this world like never before and we are eternally grateful for the way God shaped our hearts during this remarkable journey. Our son, Abel, is absolutely our greatest joy and the light of our lives!

    Some of my other passions include reading, spending time outdoors, anything “artsy” or “crafty,” 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: my husband, Nathan, and I have been married for 12 years and, along with our son Abel, our other family member includes our yellow Labrador, Murray (who has been a part of our family for all 12 years!)

    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.

  • Miss Kati Luchterhand, 4th 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. Julie Arndt, 5th Grade Teacher

    My name is Julie Arndt. I graduated from college with a Bachelor’s Degree in elementary education. This is my thirteenth year of teaching, nine of which were here at Concordia. I’ve previously also taught preschool, 2nd, 3rd, and 4th grades in Minnesota and Wisconsin. I’m also a pianist and organist.

    My husband of 31 years, Richard, and I have a 29 year old son, Jonathan, who attended Concordia for preschool – 3rd grade. I treasure my time with him and his wife and my grandson and granddaughter! My husband and I also enjoy relaxing on our patio, biking, fishing, reading and travel.

    My hope, as I instruct children, is that they will grow in academic knowledge, and more importantly become more confident and comforted in the knowledge that God loves them and has a well-designed plan for their lives.

    My wife, Dena and I are blessed to have our daughter, Sophia as a 2012 alumna of Concordia, Dena and I served as parent volunteers and I served as the Athletic Director at Concordia through 2012. Having been active at Concordia, I am familiar with many of the staff and families as I return to Concordia as the Seventh grade and Math teacher in 2016.

I look forward to equipping your children with the necessary knowledge, hard and soft skills, a love for Christ (and math) that will allow your children to be successful in high school and productive members of our community.

    I graduated from Concordia University St. Paul, Minnesota with a degree in Liberal Education, a major in Family Systems Study and a certification as a Director of Christian Education. I have served at Immanuel Lutheran Church and School in St. Charles, Missouri; Zion Lutheran Church and Preschool in Kalamazoo, Michigan and Bethel Lutheran Church and School in Gurnee, Illinois.
