Principal Elizabeth Milder is the principal of Jefferson County Middle School.

She is voiced by Mackenzie Phillips.


Elizabeth Milder is a very calm, controlled person who attributes some of her strength to the fact that she is a middle school principal. She often seems very cynical towards the people and situations around her.

She has many 'I knew a kid' stories that she uses to give warnings, although the stories themselves don't seem to have a conclusive ending.

She tends to take an active approach to Murphy's Law, going out of her way to prevent it if she can. This is seen when she makes an agreement with Milo that he can use the music room in exchange for never walking past her office again and the fact that she's very much aware of the fact that Milo promised never to show up at another sports game.

Physical Appearance

Principal Milder has an olive skin tone, prominent lips, and a thin face with a pointed chin, a sharp nose, and brown, almond-shaped eyes. Her hair is shoulder-length and brown with short bangs. There are deep lines under her eyes.

She wears a light beige shirt with a collar that ends in a bow over her chest alongside a long, knee-length beige skirt that has a large checkered pattern. Her high heeled shoes match her shirt.


In "Rooting for the Enemy", 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 sees 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 "School Dance", Zack considers telling her that vampire hunters have infiltrated the school dance to hunt down Mr. Drako before hearing how crazy his idea is.

In "The Math Book", she gives Melissa the key to a classroom to retrieve her Math textbook.

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.

In "Some Like it Yacht", she became the leader of the feral faculty. Her leadership was later challenged by Coach Mitchell.

In "Picture Day", she is seen watching the students have their pictures taken with Kyle Drako and even comments on his paleness.

In Cake 'Splosion, she is seen announcing the host of Cake 'Splosion, Basil Bravo, to the student body.

In "Ride Along Little Doggie", Principal Milder hosts the Winter Break Awards being held at the school. When Milo is unable to make it in time to get his award, she decides to stall by attempting to tell jokes.


Milo Murphy


Milder is acutely aware of the disaster surrounding Milo. Often, she'll try to avoid Murphy's Law altogether, confronting him when he shows up at a football game after promising never to do so again, and telling him he could use the music room in exchange for 'never walking past her office again'. After disaster strikes the school yacht during a field trip, Milder refers to Milo as 'The Walking Disaster Magnet'.

Otherwise, she tends to be quite polite and friendly with him, treating him as she does any other student.

Elliot Decker

When looking for a new safety inspector, Principal Milder was forced to hire from within. Since Elliot works for the school as a volunteer crossing guard, she gave him a chance to prove himself before getting the job. Instead of keeping the school safe, he hid the disasters from her while spying on Milo. She was visibly frustrated to find that he'd left the school environment less than safe and promptly fired him without having given him the job in the first place.
