After obtaining his PhD. in philosophy from the University of Rome, he emigrated to Mandate Palestine in 1927. He worked in orange groves in Rehovot and soon helped found kibbutz Givat Brenner. As an enthusiastic socialist, Sereni was also active in the Histadrut trade union. He was a pacifist who advocated co-existence with the Arabs and integration of Jewish and Arab society.
Sereni was sent to Europe in 1931-1934 to help bring people to Palestine through the Youth Aliyah, and was arrested briefly by the Gestapo. He helped to organize the Hechalutz movement in Nazi Germany and was also involved in helping to smuggle money and people out of Germany. Sereni was also sent to the United States to help organize the Zionist movement there.
