After studying for two years he was summoned to officiate for the High Holidays in Grande Templo Israelita of Rio de Janeiro, Brazil. Since the Rio de Janeiro community did not allow the participation of women singing at the services, Diego prepared all the services with a four part a cappella masculine choir.

After High Holidays services in Brazil Diego got back to Buenos Aires and was summoned by Rabbi Sergio Bergman to join the Fundación Judaica Network as Hazzan of the first and most recognized Synagogue in Argentina: the Congregación Israelita de la República Argentina (CIRA), also known as Synagogue of Libertad Street.

Diego worked for 9 years at the Congregación Israelita de la República Argentina. He was involved not only in the musical and educational program of the Synagogue but also in the social action initiatives. In 2001, when the economic crisis hit Argentina and nearly 60,000 Jews were living below the poverty line because of the ravished economy, Diego joined forces in the Shabbes Tisch Program developed with the support of the URJ together with the WUPJ (click here to learn more about the Shabbes Tisch Program)

During his 9 years working as Hazzan in Argentina, Diego participated in more than 200 weddings, prepared more than 100 B’nai Mitzvah students and sang in numerous Jewish oriented and inter-religious concerts including the special Hanukkah & Christmas Holiday Concert held at the Buenos Aires Metropolitan Cathedral. He gave classes on Jewish prayer, theology, history and Jewish education. He was responsible for leading Shabbat, Chagim (festivals) and High Holidays worship services together with Rabbi Bergman. He also performed life cycle events, adult education and worked at the Bar/Bat Mitzvah program. During times Rabbi Bergman was away, Diego was in charge also of leading the complete religious services. Finally, in his last Yom Kippur service in Argentina before moving to Hong Kong, Diego sang Kol Nidre in the presence of Cardenal Jorge Bergoglio (today Pope Francis)

In 2008 Diego was called to direct the Youth Program of the Kinnor Foundation. The Kinnor Foundation prepared a yearly special program with prestigious musicians from Argentina and abroad in order to raise money for developing a young orchestra with kids under extreme poorly conditions. Thanks to the Kinnor Foundation children were able to receive instruments, free classes and even the possibility to perform some pieces of their repertoire as guests artist before the main artists.

In the search of new challenges and locations to help in the growth of the Jewish community, since August 2010 Diego is working as Hazzan & Programming Assistant at The United Jewish Congregation in Hong Kong.
