Eleftheria Mathiasou was born in Naxos in 1978. From a young age, she developed a love for art and creation. This led her to study graphic design at AKTO in 1995, studies which she did not complete due to her professional establishment in the banking sector. She remained there for 17 years (1997–2014), during which she completed studies in economics and received certifications in financial and insurance intermediation. Since 2016, she has been exclusively involved in painting and the creation of handmade works. In her store (“With a Brush”) in Naxos, she creates paintings and paints t-shirts, sandals, bags, etc., while also crafting jewelry and seasonal decorations. She lives and works in Naxos, continuing to evolve artistically.
