about me

Let me introduce myself, I am Karl Müller. My Friends and Family will describe me with contrasting faces. Myself, I would describe myself as being unafraid of change, insatiable in intellectual curiosity, interested in big things and happy in small ways. 

My thought

of the moment

This picture of me and my nephew Sinan was taken on a cold december evening in 2017 in front of our Joya Shop in Roggwil. This Shop has moved to a different location, my nephew does not need to hold my hand anymore - he likes to wrestle with me. Time passes!
