Mrs. Joannie Kalina

District Administrator

Welcome to the 2023-24 school year!  I am confident that it will be another exciting year of learning at Erin School. I am thrilled to have the privilege to serve Erin School as your District Administrator.

Our theme this year is Growing Healthy Habits. One of my favorite parts of working in a 4K -8 district is watching our students grow through the years and leave us prepared as they enter their high school journey.  Tiny seeds make mighty trees is one of the symbolic sayings reminding us that growth takes place in different ways for each child. This year we will be working on all types of heathly habits ranging  from how we treat each other to goal setting!  We are striving for 1% better each day.  As usual, Mr. Mueller and our Fuel Up team will have a school song and dance to help us celebrate our accomplishments!

Embracing the strengths of our staff and community, Erin teachers continue to work together to create an engaging learning environment. Our teachers continue to clarify our “guaranteed curriculum,” one that all students experience as they grow and learn at Erin School.  It is an exciting and challenging time in education as we prepare students for a world we can only imagine and a world we all can make better if we choose to do so.

I joined the Erin team at the start of the 2008-09 school year. Previously, I worked as the Director of Instruction for the Kewaskum School District and was a former middle school teacher in both Brown Deer and Waunakee School District. I hold a degree in Elementary/Middle Level Education from the University of Wisconsin-La Crosse and have a Master’s degree in Educational Leadership from Cardinal Stritch University and a Superintendent license from Concordia University.  My husband and I live in Slinger with our four, active children and our one really energetic black lab.  I am humbled by the responsibilities of this leadership role  I enjoy partnering with our dedicated school board and staff to provide the very best for our children.

Beliefs that guide my work include:

  • Teachers have the most significant influence on student achievement within the classroom.
  • Parents are important partners in helping students meet their full potential.
  • While all children have different strengths and needs, they all can learn and will grow after spending time in the classrooms at ERIN school.
  • Learning should be fun and engaging!
  • Education is an investment in OUR future!

I look forward to a year full of  teamwork, high-quality learning and growing healthy habits for each and every student at Erin School!

Mr. Nick Frank

Positive School Environment:  Erin’s commitment to positivity is everywhere. Our community and family events, concerts and programs, and ample opportunities for extracurriculars create a positive and enriched environment. Let’s celebrate our successes and support each other throughout another year together. 

Here’s to another year of growth, discovery, and endless possibilities at Erin School!

Mrs. Donna Runte

Administrative Assistant/Office Supervisor

As the Administrative Assistant to the District Administrator and Office Supervisor, my job requires much diversity. First is to promote the school and educational philosophy of the Erin School District. I work closely with the District Administrator to prepare information for the School Board and in preparing required Department of Public Instruction reports. Second is to tend to daily tasks such as preparing correspondence, scheduling meetings and taking phone calls. Finally, I maintain our student software system, updating the District Webpage, placing purchase orders, arranging bus transportation, maintaining student files and assisting staff as much as possible.

As the Office Supervisor, my duties are to oversee office staff and tend the front office by greeting students, parents and visitors. Answering the phone, attending to sick children and general office duties are also part of my day.

Cheryl Johrendt

District Bookkeeper

In my position as District Bookkeeper, I am committed to promoting the school and educational philosophy along with maintaining a fiscally fit budget. In doing so, I am responsible for a wide range of duties such as accounts payable, accounts receivable, account reconciliation, budget preparation and monitoring, cash flow and investment options along with various reporting requirements and audits.

Also at Erin School District, this position handles all Human Resources responsibilities.   These range anywhere from payroll, administering insurance and other employee benefits, new employee paperwork, various reporting requirements.

Being in a small district allows me to wear many hats.   As Finance and Human Resources are my main job functions, I also help out when and where needed. As my office is located near the front office, I often help with greeting visitors, answering phones, helping sick or injured students.
