He completed his theological studies in Eger. He was ordained a priest on June 25, 1911. He arrived in the United States in 1925.
In 1927, after becoming involved in an embezzlement scandal, he left for an unknown location; the Archdiocese of Esztergom prohibited him from administering the sacraments. According to records kept by his family, correspondence with him ceased in 1926–27, and all the family’s attempts to learn anything about his fate proved fruitless.
