My story

Mateja Malnar Štembal

5 March 2025

Mateja Malnar Štembal is a historian, communicator and advocate whose life journey is a testament to resilience, optimism and a passion for making a difference. With a career spanning over 25 years in government communications and three years in corporate business, Mateja has honed her expertise in crafting impactful narratives. As the co-founder and president of ONA VE (SHE KNOWS), a non-governmental organisation dedicated to empowering women to take centre stage in media and public discussions, she has become a powerful voice for gender equality and representation.

Her personal story is one of perseverance. At 30, shortly after becoming a mother, Mateja faced a severe health challenge: a tumour that required urgent surgery. Although benign, it led to the removal of multiple organs, including her left kidney, part of her pancreas, stomach, and intestines. In 2021, she was diagnosed with diabetes, a condition she now manages with insulin and an active lifestyle. These experiences have shaped her perspective on health and sparked her passion for raising awareness about chronic illnesses.

She believes in listening to the body, making informed choices, and embracing life fully. Her golden retriever, Lars, is both her constant companion and motivation for staying active, as their daily walks help her maintain balance and well-being.

Her life philosophy is simple: live fully, inspire others, and never stop striving for a healthier, happier future.

My name is Mateja Malnar Štembal. As a diabetes patient and advocate, I am deeply committed to empowering individuals to embrace life fully while managing chronic conditions. Drawing from my personal journey and professional experience, I strive to raise awareness, foster education, and inspire proactive approaches to health, demonstrating that with the right mindset and actions, a full and vibrant life is always within reach.

“Rather than dwelling on what we can’t do because of illness, we should think about what we can do for our health. With diabetes, you can live a full life — it can even be a push toward healthier living.”
