Maestru is the leader of a singing group that meets weekly at the community center. He is also the coordinator of the town's theatrical performances. His somewhat strict demeanor can make him come across as uptight, but he is courteous to everyone he meets. Maestru's name is a play on the word "maestro."
Maestru has fair skin and blue-green eyes. His hair is black with streaks of gray. Maestru's index finger is always extended and acts as a conducting baton. He wears a black bow tie.
Maestru has appeared in two episodes of Oobi: "Theater!" and "Sing!"
