On 2011, Nico Riethmüller gathered a group of 20 young Jewish students and professionals and founded El Diario Judío www.eldiariojudio.com, a new Jewish blog site based on social critic. Over the years, he has gathered more than 350 Jewish writers from many different countries and has published more than 1500 opinion articles, building a new communitarian frame based on diversity and pluralism. But besides the blog, El Diario Judío is hosting many different educational activities, seminars and retreats for a diverse Jewish audience, bringing content and debate, even including a weekly interview which Nico himself conducts. Through El Diario Judío, which was built after Nico participating in two ROI Summits, he has organized one of the most progressive active Jewish communitarian frames in Santiago, Chile.
By coincidence, Nico ended up being in charge of officiating traditional religious services for Yom Kippur for the Jewish Community in Temuco, the oldest Jewish Community in Chile and the first synagogue in the country, on the year 2008. He has done it for the last 11 years, carrying always a group of madrichim with him. On 2014, he spent half of the year travelling through Bolivia and Argentina, where he visited different Jewish communities and discovered how much he enjoyed singing, especially officiating Kabalat Shabat religious service. On 2016, he officiated his first funeral, experience which ended up convincing him to become a Rabbi. On 2017, he started studding at Seminario Rabinico Latinoamericano, where he is finishing a degree on Jewish Studies. On 2020, he started studding at Instituto Reformista IIFRR to become a Rabbi in the reform movement, one of the very few in Chile. He strongly believes in the possibility for couples between Jewish and non-Jewish persons to get marry, and to embrace it as a new way to relate and approach with the rest of the society. He has already celebrated his first two weddings, and is preparing his next two. He strongly identifies this necesity in at least half of his Jewish friends.
Having his degree in Sociology, Nico has worked in many different organizations on Jewish Education. After his years of madrich in a conservative Jewish youth movement (Tikva), on 2007, Nico joined the Department of Education of the Jewish Agency in Chile. In 2008 and 2009, he was the Representative of Hashomer Hatzair Chile. In 2008, Nico was elected President of the Young Zionist Federation. From 2011 to 2013, he sat on the Board of the Jewish Students Federation in Chile. On 2013, he tought Modern Jewish History at the Hebrew Institute in Santiago. On 2018, he worked as Director of Youth Department for the Jewish Community Bnei Tikva in Buenos Aires. He has given classes and educational activities for every Jewish youth movement in Chile, and also several in Argentina.
