You probably know Ariel Winter as the brainy, dry-witted Alex Dunphy from Modern Family. It’s a role she played for over a decade, basically growing up on camera. But if you grew up in the mid-2000s, you’ve likely heard her voice hundreds of times without even realizing it. Long before she was navigating the chaos of the Dunphy household, she was a core part of the most elite organization in Danville.
Ariel Winter Phineas and Ferb connections run deep, primarily because she voiced Gretchen, the red-belted, glasses-wearing member of the Fireside Girls.
It’s easy to overlook voice work in a show as fast-paced as Phineas and Ferb. The show is a fever dream of musical numbers, platypus fights, and "Where's Perry?" gags. But Gretchen wasn't just a background filler. She was often the intellectual heavy hitter of Troop 46231.
The Brains Behind the Beret
Gretchen is frequently cited by fans as the smartest member of the Fireside Girls, second only to Isabella herself. Ariel Winter brought a specific kind of earnest energy to the role. Honestly, there’s a funny parallel between Gretchen and Alex Dunphy. Both are short-sighted, highly intelligent, and often have to repeat themselves because the people around them can't keep up with their vocabulary.
Remember the episode "Isabella and the Temple of Sap"? That’s a huge one for Gretchen. She basically takes the lead on the dialogue, dropping words like "sesquipedalian" just because she can. It’s peak Winter.

Winter started voicing Gretchen in 2008. She was only about ten years old. Think about that. While most kids were figuring out long division, she was recording lines for a Disney juggernaut. She stayed with the role for years, appearing in the 2011 movie Phineas and Ferb the Movie: Across the 2nd Dimension and even the 2015 "Act Your Age" special.
More Than Just One Character
Most people think Winter only played Gretchen. Not true. She actually voiced a character named Wendy Stinglehopper in the Phineas and Ferb Christmas Vacation special. It’s one of those "blink and you'll miss it" credits, but it shows her versatility even as a child actor.
The range is actually pretty wild when you look at her full Disney resume:
- Gretchen: The nerdy Fireside Girl.
- Sofia the First: The titular princess in the massive Disney Junior hit.
- Marina the Mermaid: A recurring role in Jake and the Never Land Pirates.
The Ariel Winter Phineas and Ferb legacy is built on her ability to sound like a capable leader. In episodes like "It’s No Picnic," Gretchen is the one who takes over the troop when Isabella is distracted by Phineas. She has this specific authority in her voice that feels earned.

Why We Are Still Talking About This in 2026
You might wonder why a voice role from nearly twenty years ago still gets traction. It’s mostly because Phineas and Ferb never really died. With the series revival announced and new episodes hitting screens, fans are looking back at the original cast with a lot of nostalgia.
Ariel Winter’s career has been... complicated. She’s been very open recently about the trauma of being a child star and the "dark side" of the industry. In interviews from late 2025 and early 2026, she’s discussed the pressure of growing up in the spotlight. For many fans, her voice work as Gretchen represents a purer time—before the tabloid headlines and the intense scrutiny of her personal life.
Gretchen was a character who was celebrated for being smart. In a world that often picks apart female celebrities for their looks, Gretchen (and Alex Dunphy) stood for something else. They stood for the "A" student.
The "Act Your Age" Transition
One of the coolest things the show did was the "Act Your Age" episode. It skipped forward ten years to show the characters as teenagers heading to college. Most of the Fireside Girls got new voice actors to reflect their older age.

But not Ariel Winter.
Along with Adyson's voice actress, Winter was one of the few who stayed on to voice the teenage version of her character. It gave the episode a sense of continuity. It also proved that her voice, while recognizable, had enough depth to transition from a ten-year-old scout to a college-bound young woman.
