Our Team

Sibylla Shekerdjiska-Benatova

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 and Development Manager

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.
