Leah Karchnak (Miss Leah) is a freshman at York Suburban High School. There she enjoys reading historical fiction, speaking French, and writing about herself in the third person.

In 2004 Leah came to Gary Ronemus's Stuio for the first time. She took her first class because her mother suggested it. However, she stayed for the individuality and innovation that Kenpo applies to self defense.

As soon as she was able, Leah began to teach other students at the studio. She enjoys talking with her students as well as teaching them, and is consistently shocked by their positive attitudes and thought provoking questions.

Leah can be found at the studio Tuesdays, most Thursdays and on Saturdays from 8:30 to 2:00, often playing freeze-tag or doing the chicken dance.
