Attorney Damjan DeNoble is an immigrant himself, having been forced to move to the U.S. from Sarajevo during the period of the wars in the former-Yugoslavia. Along with his family he has experienced the full gamut of the American immigrant experience, from leaving everything behind as a refugee and successfully navigating the visa and citizenship process, to finding success in America.
