Honestly, if you only know Andrea "LA" Thoma as the woman on Grant Gustin’s arm at red carpet premieres, you're missing the coolest parts of her story. She isn't just "the wife" of the guy who played the fastest man alive. She's a literal doctor. While Grant was busy sprinting through the multiverse on The Flash, LA was building a career as a high-end physical therapist and a fitness entrepreneur.
The couple has been married since 2018, and they’ve since expanded their family with two kids, Juniper and Arthur. But the way they got there? It’s kind of a wild mix of a beach proposal that went a bit sideways and two very different wedding ceremonies that spanned across the globe.
Who is Grant Gustin's wife?
So, who is she exactly? Andrea Thoma—most people call her LA—was born in Ohio back in 1988. She isn't a Hollywood actress, though she definitely moves in those circles now. She’s a Doctor of Physical Therapy. She went to Kent State University for her undergrad, where she played Division 1 soccer. You can still see that athlete mentality in how she carries herself. After Kent State, she went over to Old Dominion University to snag her doctorate.
Basically, she’s an expert in how the human body moves. She hasn't just kept that knowledge to herself, either. She founded Dare To Be Active, which is a digital fitness platform. It’s not just "influencer workouts." Because she’s a PT, she focuses on the actual science of movement—helping people get active without wrecking their joints.

A Career Built on Movement
LA’s client list is actually pretty impressive. She’s worked with people like Camila Mendes and even some of Grant’s former co-stars like Danielle Panabaker. She spent a lot of time splitting her life between Los Angeles and Vancouver while The Flash was filming. It’s a lot of hustle.
The Proposal That Almost Didn't Happen
The story of how they got engaged is pretty funny. Grant had this whole elaborate plan to propose while they were in a movie theater, but the timing got messed up because of his filming schedule. He ended up just doing it on a whim during a workout on the beach in April 2017.
He literally just pulled the ring out while they were exercising. She thought he was joking at first. He wasn't. They’d only been dating for a little over a year at that point, but when you know, you know, right?

Two Weddings and a Global Celebration
They didn't just have one wedding. That would be too simple.
In December 2017, they traveled to Malaysia, which is where LA’s mother is from. They had a traditional Kadazan ceremony to honor her heritage. There were some rumors online that they’d actually gotten "secretly married" then, but Grant eventually hopped on Instagram to clarify. He told everyone it was a symbolic ceremony to honor her ancestors and that the "real" legal wedding was still a ways off.
That official wedding happened a year later, on December 15, 2018. They tied the knot at Valentine DTLA, which is this gorgeous, historic 1920s venue in Los Angeles. It was a massive event. You had The Flash cast there, plus people like Melissa Benoist (Supergirl) and Daveed Diggs.

Life as a Family of Four
The Gustin household has gotten a lot noisier lately. They welcomed their first child, a daughter named Juniper Grace Louise, in August 2021. Then, in September 2024, their son Arthur James Grant arrived.
One thing that's pretty respectable about them is how they handle their kids' privacy. They share photos of the kids on Instagram, but they almost always cover their faces or shoot from behind. LA has talked about this before—she feels strongly that the kids should get to decide if they want to be public figures when they’re older. It’s a grounded approach for a couple that lives in the spotlight.
Managing the Hard Stuff
It hasn't all been perfect, though. When LA was pregnant with Juniper, she dealt with hyperemesis gravidarum. If you don't know what that is, it's basically extreme, debilitating morning sickness. She was pretty open about how rough that was, which honestly helped a lot of other moms feel less alone.
What You Can Learn From LA Thoma's Approach
If you’re looking to follow in her footsteps—either in fitness or just in how she balances a high-profile life—there are a few takeaways:
- Prioritize Function Over Aesthetics: Her fitness brand, Dare To Be Active, is about moving because it feels good and keeps you healthy, not just looking a certain way.
- Respect Your Roots: The way she integrated her Kadazan heritage into her marriage journey shows a deep respect for family history.
- Set Boundaries: Even if you share your life online, you don't have to share everything. Protecting her children’s privacy is a choice she’s stuck to consistently.
If you're interested in her workout style, check out her YouTube channel or the DTBA app. She often posts 5-to-10-minute "movement snacks" that are great if you're stuck at a desk all day. You don't need a superhero's metabolism to start moving better; you just need to be consistent.
