Growing up reading Suske en Wiske, Sandor dreamed of a career as a cartoonist from an early age. At the age of eight he invented his own cartoon character, invented stories, drew and put together his own comic books. In high school he enjoyed secretly drawing teachers in caricature during classes and thus his first steps as a caricaturist were taken. He was soon asked to also draw live at parties. After studying at the Art Academy, Sandor ultimately chose to focus entirely on drawing caricatures, cartoons and a few comics.
After working alone for a number of years, he joined forces with colleague and friend Harold Hugenholtz in mid-2023.
