Growing up, Kathleen always loved Sesame Street and Muppet-style puppetry but never thought of herself as a performer. She eventually pursued a career behind the camera in production. While working as a story producer in reality TV, her husband encouraged her to take a “puppetry for comedy improv” class with him which reignited her love for the craft. In 2014, she was accepted into a Sesame Puppetry Workshop where she met and trained with some of the industry’s top puppeteers. Between Sesame Street’s seasons 46 through 48, Kathy was brought on as a puppetry assist and to attend additional workshops. Then in 2017, she was one of four new performers invited to join Sesame’s first Mentorship Program in an effort to train the next generation of puppeteers. Since then she has taken on the role of Elena, Julia’s mother. And in 2021, she was given the first Asian-American Muppet character on Sesame Street, Ji-Young, who was created as part of Sesame’s new commitment to teaching racial literacy. Some of Kim’s other credits include Helpsters on Apple TV+, SNL, the Today Show, Awkwafina is Nora from Queens as Toe-Knee and A Beautiful Day in the Neighborhood.
