Principal Milder is the principal of Milo's school. And like the majority of Danville residents, she is very much aware of the trouble that follows Milo around.
Principal Midler is a middle aged woman with shoulder length brown hair and olive skin.
She wears a light beige shirt, a long beige skirt, and beige high heel shoes.
Principal Milder is a calm person, which she claims comes from her job as a Middle school principal. However like everyone else she is some-what unsettled by Murphy's Law.
Principal Milder first spoke in Rooting for the Enemy where she was surprised to find Milo at the game, having heard that he had promised Coach Mitchell that he wouldn't attend another game after previous mishaps. After Melissa and Milo explained that the coach had given his okay and announced his belief that their team would lose the game at the pep rally, Milder remarked "Did he now? I need to explain pep to that man."
In Athledecamathalon, she see Milo's parents dropping off his lunch and body armor. She takes them to deliver to Milo, but was crushed by the weight of the body armor.
In Disaster of My Dreams, she considers Elliot Decker for JCMS' safety inspector, but fires him, but Elliot points out he didn't get hired yet, so she doesn't hire him since his bike and the boulder damaged her car.
