Our Team

Sibylla Shekerdjiska-Benatova

A Book A Day Founder & Executive Director

Building libraries and collecting books is a passion best shared. My hope is that our selection of books will promote an appreciation for children’s literature and will develop visual literacy among young readers.


Erin Seifstad

 Administrative Assistant

Erin believes that narratives from diverse voices have the power to open minds, foster empathy, and validate all identities through representation. As the daughter of a school principal, Erin grew up among the stacks of her school library in Istanbul, Turkey. Stories were her windows into countless real and imagined worlds, and she is proud to be part of a team working to open these windows for children today.

Alumni

Soyoung (So) Jung, Senior Assistant Manager

So joined A Book a Day in 2018 as a graduate assistant. Being a part of ABAD’s team is extremely rewarding because it offers chances to children who may not have easy access to a home library or up-to-date books. As an immigrant who came to this country at the age of four, So hopes to contribute her knowledge and experience to make improvements to equal opportunity and awareness of the importance of children’s literature. So works at a consulting firm in Philadelphia and had previous experience at a nonprofit for seniors. She received her undergraduate degree in Development Sociology at Cornell University and her master’s degree in Social Policy at the University of Pennsylvania. 

Iman Tednga, Undergraduate Assistant

Iman is a freshman at the University of Pennsylvania studying Philosophy. He works at the LGBT Center in partnership with A Book A Day. The reason they chose to be part of this program is to help young children see themselves in literature and be able to have incredible role models they can actually relate to!

Minnie Jung, Program Manager

Minnie graduated from the University of Pennsylvania with a Master’s in Social Policy in 2021. Her work at A Book a Day ultimately informed her academic interests in education policy, where she is currently interning at the Office of Children at Families in Philadelphia supporting education initiatives in the city. She urges you all to have confidence in your voices and stories, be curious about your roots and histories, and be willing to listen to those around you — meaningful education comes in all shapes and forms, and when you least expect it.
