EarthKosher was founded in Los Angeles, California in 2004 by Rabbi Zecharyah Tzvi Goldman and his wife Mrs. Ora Ahuva Goldman. Rabbi Zushe Yosef Blech initially served as EarthKosher's Rabbinic Consultant. In 2007, before EarthKosher began its expansion, he became a full partner and the Senior Kashrut Administrator. As such, he is responsible for the oversight of all companies under kosher certification and the analysis of all kosher standards and policies applicable to these companies. EarthKosher formed a partnership in 2009 with Rabbi Nissim Hilu of Mexico City, Mexico and now operates a full Spanish speaking kosher certification branch in Mexico.

As of July, 2011, EarthKosher provides kosher certification to 150 companies in 17 countries.
