claudia_crop_0.jpgClaudia Rozenberg, Early Childhood Center Director

Claudia Rozenberg has been in early childhood since 2006. She has taught in a variety of school settings over the years both here and abroad. She believes that children develop skills in preschool that they use their entire lives and feels that a positive first school experience is the key to a child’s school success. She knows a child's family and community are key to that child's success and therefore holds those relationships paramount.

Claudia holds a Master’s degree in Early Childhood Education from Erikson Institute in Chicago and is a certified teacher in the state of Illinois. She holds a second Master’s in French culture and civilization from Middlebury College.

Claudia is very excited to become part of the JRC community and bring her family into the community as well. She lives in Lincoln Park with her husband Barry and her two daughters, Clara and Naomi.

The Green Synagogue and the Pillars of Chai


In 2008, we built the first platinum LEED-certified green synagogue in North America. The construction required 18 pillars - the number in Hebrew that also means "chai" or "life." 

Now, more than ten years later, JRC has launched the Pillars of Chai Campaign to raise $4.4m to wholly own our beloved building.
