Schneider spent her formative years on a
Chippewa reservation in
Bemidji, Minnesota with her two older brothers in a mostly
Jewish family. She moved to New York at the age of 8. Her father became a
math and drama teacher at the School of Arts High School in
Rochester, New York, where she graduated as
salutatorian. Her mother was an attorney for the reservation. She started playing violin, which she learned from her grandfather, learning the
Suzuki method,
IT'S MY PARTY! From ages 7–20, she went to
Jewish summer camp, becoming a counselor, and started performing on stage. By the time she was in the
fourth grade she began writing and performing her own plays, because the teacher told her that she would only be allowed to stage a play if she "wrote, produced, directed." Four years later she was chosen for a part in
Annie; Schneider's parents would not let her tour with the troupe after being cast. While in college she continued going to auditions and got the role of Sheila Brentwood in the television series
The Amazing Live Sea Monkeys. For the show she was allowed to cast the actors who played her parents. After the show got canceled, she replaced
Alanna Ubach as the assistant and co-host for the second and third seasons of ''
Beakman's World''. ==Dialect research and stage shows==
