If you’ve been watching NBC’s mockumentary St. Denis Medical, you already know the vibe. It’s chaotic. It’s underfunded. It’s basically what happens when you take the DNA of The Office and Superstore and drop it into an Oregon emergency room that’s held together by duct tape and sheer willpower. But amidst the veterans like Wendi McLendon-Covey and David Alan Grier, there’s one character everyone keeps talking about: Matt Pearson.
Mekki Leeper, who you probably remember as the "nerd" from Jury Duty, plays Matt. He’s a newly minted ER nurse, and honestly, he’s kind of a mess in the most endearing way possible. But there is a lot more to St. Denis Medical Matt than just being the "lovable idiot" of the ward.
The Weird, Religious Backstory You Might Have Missed
Matt isn't just a suburban kid who decided to go to nursing school on a whim. His backstory is actually wild. He grew up in a strict, isolated religious community in Montana—think less "Sunday school" and more "prepping for the secular world to destroy itself."
His full name? Matthew Ebenezer Charles Jedediah Pearson.
Because of that upbringing, Matt has these massive blind spots about how the normal world works. He didn’t grow up with modern medicine, which makes the fact that he’s now an ER nurse both hilarious and a little bit inspiring. He’s constantly playing catch-up with culture. It’s why his enthusiasm is always cranked up to an eleven; he’s genuinely excited to be there, even when he’s getting yelled at by a grumpy patient or accidentally saying something completely unhinged.
Leeper has mentioned in interviews that he doesn't play Matt as "stupid." He plays him as naive. There’s a big difference. Matt is smart enough to pass his boards and handle medical emergencies, but he has no idea what a "vibe" is or how to handle a sarcastic coworker like Serena.

The Scars (Literally) of a Montana Farm Life
One of the funniest running gags—if you can call it that—is Matt’s collection of scars. He’s like a walking medical textbook of "things that can go wrong on a homestead."
If you look closely at his character's lore, he’s got:
- A scar on his right shoulder from being bucked off a horse.
- A mark on his chest from a grain silo repair gone wrong.
- A "plague cat" injury on his neck. (Yes, a plague cat.)
It’s these specific, weird details that make St. Denis Medical Matt feel like a real person rather than just a sitcom trope. He isn't just the "new guy." He's the guy who knows how to do "captive bolt stunning" on cattle but probably doesn't know how to use a dating app.
That Shocking Season 2 Ex-Wife Reveal
For most of the first season, we all assumed Matt was just this innocent, single guy with a massive crush on Serena (played by Kahyun Kim). Then Season 2 hit, and the show dropped a bomb: Matt has an ex-wife.
Violet Elizabeth Chastity Stokely-Pearson showed up at the hospital, and suddenly everything we thought we knew about Matt’s "innocence" shifted. It turns out he wasn't just a lonely guy pining for a coworker; he had a whole previous life in Montana that involved a marriage.

This revelation changed the dynamic between Matt and Serena. It added a layer of "wait, what else is this guy hiding?" Honestly, it was a genius move by the writers. It took him from being the "puppy dog" character to someone with a bit of a complicated past. In the episode "I Left a Woman on the Table," we see Matt trying to navigate Violet's return while still clearly being into Serena. It’s messy. It’s awkward. It’s peak St. Denis Medical.
Why the Matt and Serena "Will They/Won't They" Works
Sitcom romances can be exhausting. If they happen too fast, the tension dies. If they take too long, people stop caring. But the chemistry between Mekki Leeper and Kahyun Kim is different.
Serena is blunt, sardonic, and has zero filter. Matt is earnest, polite, and terrified of offending anyone. They shouldn't work. But they do because they balance each other out. Serena pushes Matt to have a backbone—like the time he finally stood up to a patient for being ungrateful—and Matt reminds Serena that it’s okay to actually care about things once in a while.
Mekki Leeper: From "Jury Duty" to the ER
If Matt feels authentic, it’s because Mekki Leeper is a massive talent behind the scenes. He wasn't just cast in the show; he’s actually a writer on it, too. This is the same guy who was nominated for an Emmy for writing Jury Duty.
Having a lead actor who is also in the writers' room is a huge advantage. Leeper knows exactly how to pace Matt’s jokes. He knows when to lean into the physical comedy—like Matt’s slightly-too-intense nursing "hunger to learn"—and when to let a quiet, awkward beat sit for a second.

He’s even talked about how the set at the Universal lot feels so much like a real hospital that he sometimes forgets he’s filming a comedy. That groundedness is what makes the show work. If the medicine feels (mostly) real, the jokes land harder.
How to Watch St. Denis Medical and Catch Up

What’s Next for Matt?
As we head deeper into the current season, the big question is whether Matt will finally move past his "ex-wife baggage" and make a real move on Serena. The show has a way of throwing curveballs, like the recent "fake British drama" prank they played on Bruce, which showed that Matt is becoming more of "one of the gang" rather than just the naive outsider.
Actionable Insights for Fans:
- Watch for the Background Details: Many of Matt’s funniest moments are subtle reactions in the background of a scene.
- Follow Mekki Leeper: Since he’s a writer, his social media often gives tiny glimpses into how they develop Matt’s weird Montana lore.
- Rewatch the Pilot: Now that you know about his ex-wife, Matt’s behavior in the first few episodes hits a little differently.
The genius of St. Denis Medical Matt is that he represents all of us starting a new job—totally out of our depth, trying too hard, and hoping no one notices we have no idea what we're doing. Whether he's dealing with a "plague cat" or a complicated crush, he’s the heart of the hospital.
