Born in Lodz, Poland, in 1981, Miko studied ballet, voice, and piano at Poland's Chopin Music School before a choreographer recruited her at the age of 14 to move abroad and join the School of American Ballet. Relocating to New York, Miko studied at the New York City Ballet and the Lee Strasberg Institute before a back injury brought her dancing career to a halt. Moving back to Poland and appearing in numerous films in the following few years, Miko moved back to the United States in the mid-'90s and, with her acting experiences intact, began to make a bid for the big time on the silver screens of Hollywood.
