Full Resume

Welcome, my name is Sebastian Sobolewski. I was born in Poland in 1975 under communist rule. My father was an activist in the “Solidarity” movement that rose to eventually free Poland from the communist regime. In 1984 my family was granted political asylum in the United States, so we immigrated to escape Political persecution. It allowed us to start our lives from scratch.
