Bergara was born in Bilbao, Biscay. Having emerged through Athletic Bilbao's prolific youth ranks, Lezama, he made his first-team – and La Liga – debut on 25 February 2007, coming on as a substitute for Josu Sarriegi during a 0–3 away loss against FC Barcelona, but spent the vast majority of his stint at the club with the reserves.
In summer 2008, Bergara was released and joined Basque neighbours Sestao River Club, in the third division. He continued competing in that level in the following years, mainly with CD Laudio and Arenas Club de Getxo.
