Leadership Team

Michelle Grieger, Principal


Welcome to Mannum Community College!

I have been teaching for 18 years and have been with Mannum Community College for 10 years with 2 years as Assistant Principal R-5 and 5 years as Deputy Principal R-12.

Kieran Jaensch, Deputy Principal and Senior School Senior Leader


Prior to my teaching career I completed a Diploma of Arts in Furniture Design and various trade qualifications in the Wood Working area. I then underwent a Bachelor of Education specialising in Design and Technology completing my degree in 2011. I have now been in the education system for coming up 12 years. Meningie Area School was my first short term appointment, before commencing at Heathfield High School in the Adelaide Hills where I spent 5 years teaching across a range of design and technology subject areas, managing the regional Doorways 2 Construction VET program, and leading a number of STEM initiatives. In 2017 I packed up my little family and took on the position of Senior Leader – Students Pathways in the South East, based out of Mount Gambier. This role saw me working with 11 different secondary high school sites across the South East and Tatiara regions in all things SACE, VET, student pathways and professional development for secondary education staff.

In 2018 I commenced my appointment at Mannum Community College where I have been able to draw upon all my previous experiences and knowledge across SACE, VET, STEM and student pathways as I support students through their senior schooling and onto their future career paths of choice. In my time at the school we have seen a number of changes to the school as a whole, especially the senior school. We now have new state of the art learning environments, one: one laptop device initiative, along with a great nurturing community feel to our environment. I look forward to continuing my work with MCC students, parents/ caregivers and the wider community supporting the whole school in the Deputy Principal role.

Sophie Frost, Leader of the Junior School


The Junior School provides an enriched learning environment that focuses on supporting the students in Reception to Year 5 on a journey of discovery and learning. The Mannum Community College Junior School is comprised of composite classes catering for Reception to Year 5 students. Each classroom block shares an art area and computer pods and all face out onto the lawn and playground areas.

Kathryn Hese, Middle School and Years 5-12 Literacy Senior Leader


As leader of the Middle School at Mannum Community College I bring almost 20 years of teaching and leadership experience in rural schools to the role and continue to have a passion to deliver top class rural education. As some of my experience has been in senior secondary roles I am acutely aware of the demands young people face in the SACE, tertiary education and on the employment front, and therefore aim to create a rigour and enjoyment in learning in the middle years to ensure a smooth transition and future success. Personally, I enjoy good narratives delivered in all modes and of all genres, and have taken time to develop my skills and understanding of writing through extensive practice and education, including recently completing a Master of Education with a focus on literacy and writing. Sports are another of my passions and I continue to be involved in clubs and officiating to enable sports for children to operate and deliver good healthy experiences.

Correta Odera, Wellbeing Leader


At Mannum Community College (MCC), we understand that high levels of wellbeing have the potential to bring about positive change in all members of

our school community. We know what is required to foster wellbeing, and how it can become a powerful force in students’ learning and development.

My role as Wellbeing Leader is to coordinate three levels of wellbeing support:


  • Whole school initiatives including:
    • a school-wide common language (e.g. Restorative Justice, Play is the Way Key Concepts and Self-Master Questions),
    • key curriculum areas (Keeping Safe: Child Protection Curriculum and Shine SA Relationships and Sexual Health), and
    • Special days (e.g. Harmony Day, IDAHOBIT and Grand-friends’ Day)
  • Small group programs such as Seasons for Growth, Mind Up and Student Leadership.
  • Individual, targeted interventions – usually through external mental health and allied support services.

Julie Strauss, Business Manager


I lead the business and administration operation of Mannum Community College in the areas of finance, facilities and HR. This includes funding, budgets, resource management, facilities upgrades, maintenance, community use of school facilities, coordination of events and appointment of non-teaching staff. I am the site contact for outsourced services such as OSHC and cleaning. I work with the Canteen Manager, Governing Council and Canteen Committee to oversee the operation of the school canteen.
