Jaclyn Best
- Synagogue Administrator
Email: admin3636@neveikodesh.org
Jaclyn Best (she/her) was born into Nevei Kodesh before we were even an official renewal community. She has seen Nevei Kodesh grow and evolve over three decades and is proud to return as a staff member. She is blessed to have grown up in a Renewal setting, as she feels most connected to Judaism through musical prayer and the progressive, inclusive, equitable community feel that Jewish Renewal and Nevei Kodesh embody so well.
Jaclyn recently returned to Boulder in order to reconnect with these values and practices, and is elated to be serving her community as Synagogue Administrator.
Jaclyn has spent most of her adult years working in the field of water resources cooperation and conflict, both in an academic setting and as a practitioner. She has worked in and studied water governance and management in Israel, Palestine, Jordan, the Netherlands, Costa Rica, Oregon, and North Carolina. Her passion for understanding and working with "the people side of water" is deeply rooted in the Jewish values of Tikkun Olam.
