Milo Murphy's Law Wiki

Milo: Hi Zack's mom!

Eileen: Please, just call me Dr. Zack's mom.

— Milo greeting Eileen, "Worked Day"

Eileen Underwood is Zack's mother and Marcus Underwood's wife. She works as a doctor at the nearby hospital.

She is voiced by Vanessa Williams.[1]


Eileen tends to be very sarcastic and dry, often speaking in a serious tone. When spending time with Zack on the way to a parent-teacher conference, the two of them exchanged amuzed banter, with Zack calling her 'precocious'.

Like her husband, she has a slightly different definition of roughing it while camping. Rather than spending their time camping in the woods, she stayed in a cozy lodge with her husband. She does, however, seem to enjoy adventures with her family, and had gone on a boat trip on the Saskatchewan River at one point.

Physical Appearance

Eileen has dark skin and long, thick black hair tied back with a pale purple band. She wears a pair of wire frame glasses and round gold earrings.

When at work, she wears a knee-length white doctor's coat with pockets on either side over some blue scrubs. Her sneakers are white with grey soles, and she wears a stethoscope around her neck.

Off-duty, Eileen wears a very light purple blazer over a black undershirt, which is tucked into her high-waisted pants. Her belt is a slightly darker purple with a thin, oval-shaped buckle, and she wears a pair of dark dress shoes with a bit of a heel.


In "Worked Day", her son's class came to the hospital, where Murphy's Law takes effect and turns an MRI into a super magnet that attracts all the metal the city.

In "Murphy's Lard", she is seen in a flashback with her husband and son in a pontoon in the Saskatchewan River where Zack freaks out and jumps out of the boat when a fish lands by him.

In "Perchance to Sleepwalk", she and her husband were in a spa while their son and his friends went camping.

In "Backward to School Night", she attends the Jefferson County Middle School back to school night. She, along with her son's teacher and his friend's fathers, turn into toddlers and run while with the middle schoolers trying to keep them inline. She and the others eventually return to their actual ages and reminisce when their children sleep.

In "Milo Murphy's Halloween Scream-A-Torium!", she is seen in a flashback of her pregnancy with Zack. Her husband scares their unborn child during an ultrasound.

In "A Christmas Peril", she and her husband go to a Chinese restaurant at the mall and have a meal with the Murphys, the Chases, Mort and Amanda.

In "Field of Screams", she is seen dropping of Zack and his friends off to Cornelius Underwood's farm. She is later seen standing around the table with Zack, Marcus, and others.

“Melissa: What's your specialty, Dr. Zack's mom?

Eileen: The really bloody stuff.”
—Melissa and Eileen[src]

“Okay, who wants to see the emergency exit?”

“How about we switch places? I go to school and you cover me in the ER. Just remember, the vital organs go in the inside before you sew them back up.”
—Eileen to Zack[src]
