Eighth-grade student at Stoneybrook Middle School.

In #19 Claudia and the Bad Joke, he is mentioned as a former baby-sitter of Betsy Sobak. He thought Betsy may have grown out of her practical joke tendencies but wasn't sure.

In #52 Mary Anne + 2 Many Babies , he is assigned to work with Howie Johnson in the egg parenting project because there aren't enough girls in the class.

In #93 Mary Anne and the Memory Garden, he is in a study group with Mary Anne, Barbara Hirsch, and Amelia Freeman, who dies in a car accident.
