Founding Director

I’m a rabbi and an entrepreneur and spend much of my time exploring the rich intersections between these two traditions, and the abundant possibilities therein. I'm committed to leaving behind a world that is more compassionate, connected, and just than the one I found, and - in pursuit of that commitment - I am the Founding Director of Glean Network, an incubator, and network for entrepreneurs who are building new models of faith in action, and Director of Innovation at Clal, a think-tank focused on the future of faith in America. I'm blessed to live and learn with my wife, Lizzie Pollock, and our three children, Micah, Nessa, and Ayla in Providence, RhodeIsland. I read broadly and voraciously, cook adventurously, and find sanctuary on the rock climbing walls of New England.



Assistant Director

Sandy Hong is a facilitator and a strategic consultant, with a background in digital strategy & community organizing. Prior to joining Glean Network’s Core Team, he was a participant in Glean’s 2020 START program, focusing on developing offerings that center belonging, liminality and spirituality within the Korean diaspora. 


Sandy is passionate about building resilient systems of care that shape and influence organizations and their commitments from the inside out. When he’s not working on complex organizational dynamics and systems, he can be found skateboarding or finding some other way to get wind in his hair.



Program Manager

Shelli Aderman comes to Clal from a varied and exciting background, where she started learning to code computers as a child. As an adult, Shelli continued her fascination with all things behind-the-scenes in a career of theatrical stage management and administration. As the Program Administrator for many of Clal’s varied projects, including Glean, Rabbis Without Borders, and Stand and See, she gets to use all of her backstage skills in the support of rabbis.

Within the Jewish community, Shelli has been able to put her stage management training to use as an Administrator for Congregation Tehillah in Riverdale, and Emanuel Congregation in Chicago. Also in Chicago, Shelli was the Youth Advisor and Youth Service Leader for Anshe Emet Synagogue. Shelli also is a Religious School and Youth and Family Educator at Town and Village Synagogue.

A graduate of Hofstra University and Young Judaea’s Year Course, Shelli is thrilled to be part of CLAL. Shelli is happily married to Narda E. Alcorn, with whom they share the joy of parenting Malka and Noah Matan.



Digital Storyteller

I'm a data-driven creative that loves to explore the various avenues through which we create and share information. I come to Glean with the hopes of not only broadening my understanding of the intersection between innovation and faith, but also documenting our journey in a plethora of ways. I am currently pursuing a BBA in Marketing and a minor in IT from The University of Massachusetts-Amherst, but my academic interests also include FinTech and Islamic Law. You can always find me talking world affairs, reading Emily Dickinson, or producing disruptive art - whatever that may look like. 



Belonging and Engagement Intern

I am a 2nd year Master’s of Divinity student at Union Theological Seminary, with a deep interest in the Hebrew Bible and the ways faith informs imaginings and realities with regards to diversity, belonging, and inclusion. I am excited to work with the Glean Network to embrace and engage the potential of my own sense of wonder and support the organization with my skills in facilitation, education, and care work. 


My eyes light up when I am in conversation about the pedagogical impact of educational technology, liberation theologies, Ancient Near Eastern prophecy, and ritual and spiritual practice. When I’m not studying, you might find me writing poetry, singing showtunes, or dreaming about the world I hope to co-create with all of you.
