San Epifanio, known by almost everyone as simply, "Epi", grew up in Zaragoza, and began to play the sport of basketball in his native city. In 1973, Epi made his club debut with CN Helios, in the Spanish third division. However, his local club eventually rejected him. In 1974, FC Barcelona signed his older brother, Herminio, to a contract. Herminio then insisted that Epi would also join him at the club, and so the two moved to Barcelona. FC Barcelona's senior men's team head coach, Ranko Žeravica, gave Epi the opportunity to play with the club's youth teams.
