  • Rev. Jeffrey E. Mortenson, Pastor (Faith Lutheran Church)

    Rev. Jeffrey E. MortensonGreetings! God’s richest blessings to each of you! For 21 years I have been privileged to be the pastor of Faith Lutheran Church here in Sturtevant, Wisconsin. During some of that time, I have been blessed to be the chairman of the Concordia School Board. I am thankful that the Lord has used me in some small ways to advance this outstanding ministry.

    The Lord began preparing me for this position through my undergraduate work at Concordia Teacher’s College in River Forest, Illinois (now Concordia, Chicago). There I earned a bachelor’s degree in elementary education. After completing my masters of divinity degree at Concordia Seminary in St. Louis, my first call into the pastoral ministry was to a dual parish assignment in Appleton City and Creighton, Missouri. Certainly, I was able to put my education degree to work in my preaching and teaching in Missouri for those first 11 years. However, when I got the call to be the pastor at Faith in Sturtevant, which actually supported their own grade school, I knew that God was leading me into an exciting ministry that would put to better use my undergraduate studies.

    To be trusted to supply the spiritual and secular knowledge and education for so many wonderful young people is a privilege that no one on the staff of Concordia takes lightly. It is our pleasure and privilege to serve you.

  • Mrs. Jeannine Klein, Principal

    Mrs. Jeannine KleinConcordia Lutheran School exists for the purpose of "Bringing Christ and academic excellence to our students for life and forever." The school celebrated 46 years serving the community and our Lord in 2016 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. 

  • Mrs. Cheryl Lynn Wilkinson - Secretary
    Mrs. Cheryl Lynn WilkinsonMy experience with Concordia Lutheran School goes way back into the 1970’s when I attended and graduated from this school. My two daughters both graduated from Concordia, went onto Racine Lutheran High School and are in college or graduate school. Christian Education is very important to me especially in today’s world.

    As an Administrative Assistant (i.e. School Secretary) I am involved in many aspects of the school. This is a great experience for me especially when it comes to interacting with the teachers, students, and parents. They all are a great source of information and a wealth of knowledge. Each day is a new adventure!! I could not do my job without each and every one of them.

    I look forward to coming to school to see the students learn and shine not only in their academics but also in their faith! They grow with each day through the love and guidance given by our teachers and staff. What a blessing Concordia Lutheran School is!

  • Mrs. Theresa Mierow, Pre School Director & Teacher

    Mrs. Theresa Mierow I began working with preschool students as an aide during the 1993-1994 school year. I enrolled in early childhood classes and received my two year 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 30 years. We love to camp and spend most of our summer at our camping resort in Plymouth. I also enjoy painting ceramics and I teach country line dancing two nights a week. I have been line dancing for 25 years.

  • Ms. Susan Ritacco, Preschool Aide

    Ms. Susan RitaccoI 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. Melissa Eberhardt, Kindergarten Teacher
    Mrs. Melissa Eberhardt Hi, my name is Melissa Eberhardt. I am a graduate of Concordia University Wisconsin in Mequon with a degree in Early Childhood Education and a minor in Theater.

  • Miss Kati Luchterhand, Kindergarten Aide & After School Care
    Miss Kati Luchterhand

    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. Sharon Joyce, After School Care
    Mrs. Sharon JoyceI taught Sunday School for 6 years. I started working for Racine Unified at Garfield Early Childhood for 2 years as a Special Education assistant. After that at I was also at Schulte Elementary working in the Title 1 Program for 7 years. I made my way back to Special Ed. L.D. for 7 more years. When students were assigned to regular classrooms I worked with them there but also went wherever I was needed. I did many different jobs but enjoyed them all! Well... not so much wearing the secretary hat! I retired from R.U.S.D. last December after 24 years. Speaking of Concordia… what a blessing that children can be taught in school the love of Jesus. I did miss the children, here I am!
  • Mrs. Amy Usher, Afternoon Care

  • Mrs. Phyllis Mortenson, 1st Grade Teacher

    My husband of 38 years, Jeff Mortenson, is the Pastor of Faith Lutheran Church. Our son, Andrew, is a graduate of Concordia and Racine Lutheran High. He is a financial consultant for Thrivent Financial for Lutherans. He and his wife, who is also a Lutheran teacher, have two daughters and one son.

    Christ was an important part of my life as I was growing up. Even when I was in grade school, I knew I wanted to be a Lutheran teacher someday. I count it a great privilege to be able to share God’s Word and my faith with my students on a daily basis. I am proud to follow in the footsteps of my step-father who was a Lutheran educator for 43 years.

    I graduated from Racine Lutheran High School in 1973. I attended Concordia College in Ann Arbor, Michigan and graduated from Concordia Teachers’ College in River Forest, Illinois in 1977.

    I have also taught in Lutheran schools in Palatine, Illinois and in Olivette, Missouri.

    From 1983 – 1994 we served two congregations in western Missouri.

  • Mrs. Jodi Barclay, 1st Grade Aide

    Mrs. Jodi BarclayMy name is Jodi Barclay. I grew up in a large, happy family in Iowa. I spent my senior year as an exchange student in Belgium. I then spent a few years in Alaska, Texas and Ohio before coming to Racine in 2000. I met and married my husband, Robert in Texas. We have four children (Ian, Noah, Grant and Genevieve) ages 20 to 12 and they all attended or are attending Concordia. Our oldest son, Ian, was just starting kindergarten when we moved to Racine and he started kindergarten in Mrs. Mortenson's class. Genevieve, our youngest, will be going into 7th grade this year.

    The entire family has spent many hours volunteering at Concordia and it has provided a great place for education, happy school memories for our older kids, and a place we will always support.

    We also enjoy traveling across the States visiting our extended family (none from Wisconsin) and attending Pentecost Lutheran Church where we are active members.

  • Ms. Karli Luchterhand, 2nd Grade Teacher
    Ms. Karli LuchterhandMy 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. Amanda Eckman, 2nd Grade Aide

    Mrs. Amanda EckmanMy name is Amanda Eckman. I was born and raised in central Illinois on a farm. I married my high school sweetheart almost 17 wonderful years ago. We have one daughter, Katie, who is going into 7th grade at Concordia. We spend most of our time following her sporting events.

    We moved here three and a half years ago from Florida for my husband’s job. It has been quite a change for us to get used to Wisconsin winters.

    This will be my fourth year at Concordia. This year I will serve as an aide for second grade.

  • Mrs. Korie Baganz, 3rd Grade Teacher

    Korie BaganzSince 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 twelve 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. This last school year God 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 11 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 11 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 in the coming year.

  • Mrs. Shari Schulz, 6th Grade Teacher

    Hi, my name is Shari Schulz. I am excited that the Lord has called me to Concordia. I have worked in many different Lutheran and public schools and grade levels which give me a great variety of experiences. I have taught middle school classes at two Lutheran schools in St. Louis, 4th grade at a Lutheran school in Washington State, high school in a public school in Minnesota, and 3rd/4th grade and middle school both in Lutheran schools in Wisconsin. I feel blessed to have worked with so many outstanding educators, parents, and students. I received my undergraduate degree form Concordia University, Wisconsin with an education/English major and a minor in psychology.

    I have wanted to be a teacher or a librarian since I was a young girl. In elementary school I had a playroom that had a chalkboard. In this room, I would teach my family and the neighborhood children different things I had learned or read about. When I was older I helped with Sunday School and Vacation Bible School which I still do today because I enjoy them so much.

    I am an avid reader and am passionate about literature of all kinds. I love learning new things and just reading to relax. It is my goal to equip my students to become lifelong learners who are confident and enthusiastic about reading, writing, and speaking. I also am privileged to share the love of Christ with my students and their families. I want my students to grow in their faith and to develop a servant’s heart.

    I have been married to my husband, Jeff, for twenty-three years. We have been blessed with three children: Sarah (a freshman at the University of Minnesota), Hannah (a junior at Martin Luther High), and Noah (an 8th grader at Hales Corners Lutheran School) As a family we enjoy pizza and game night, camping, biking, boating, and attending theater performances.

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. Stepping into the classroom feels more like coming home than it does like going to work. 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.
