Kulchytzkyy was born in a small and rural town of Ukraine. He started training in freestyle when he was seven years old and always had to wrestle older kids as those were the tournaments he qualified for. When he was twelve, he moved to Odessa with his coach to attend school and follow a strict training program. Since then, he had tremendous success in the Ukrainian circuit, with five National titles as a cadet and a bronze medal at the Cadet European Championships of 2008, same year in which he and other members of his family were granted the green card visa they had been looking for since years back to immigrate to the United States of America.
University
After his senior year of high school, in which he did not compete as he was considered a professional due to his accomplishments, Kulchytzkyy attended a Division III college in University of Wisconsin–Oshkosh. He's the most accomplished wrestler in the history of the Titans, having won three Division III National titles and earning NCAA Division III Wrestler of the Year honors twice. Despite of his initial wish of transferring to a Division I university, he refused to transfer as a junior and graduated with a 143-5 record, with only one loss to a DIII athlete.
