In 1984 he moved to Spain, where he has engaged in intense artistic and educational work until now. In his pedagogical activity in Catalonia, Spain, his work as Head of Piano Department at the Conservatory in Vila-seca should be highlighted. He encouraged and introduced changes in curricula and programs on piano teaching, as freedom of choice of repertoire, internal auditions and competitions, control tasks, more student concerts, outstanding students having more class time, etc. making this institution one of the most pedagogically advanced in Catalonia and the one that has brought most students to the Higher Grade. This innovative work was recognized when he was appointed Professor Emeritus in 2007 by the Conservatory of Music of Vila-seca.
His work as professor and Head of the Piano Area in the Conservatori Superior de Música del Liceu in Barcelona, from 1994 to 2002, carried the same significance because it meant a radical change in educational planning, curriculum and piano programs.

All this took place before the promulgation of the Law on Education Reform and therefore allowed the conservatory to adapt easily to new legal conditions.
