You know Kim Coates. Even if you don't think you do, you definitely do. He’s that guy with the piercing eyes who played Tig Trager on Sons of Anarchy, the dude who’s been in everything from Black Hawk Down to Waterworld. He has this intense, slightly manic energy on screen that makes you think he probably spends his weekends bare-knuckle boxing in a garage.
But here’s the thing: reality is way more wholesome. While most Hollywood marriages have the shelf life of a carton of milk, Kim Coates and wife Diana Chappell have been a rock-solid unit since the early eighties. We’re talking over 40 years. In an industry where "long-term" usually means making it to the second season of a Netflix show, that's basically a miracle.
Who Is Diana Chappell?
Honestly, Diana is the secret weapon in this story. She isn't an actress, and she isn't chasing the paparazzi. She’s a 1981 graduate from the University of Saskatchewan with an education degree.
They met back in Canada, long before Kim was a household name or a "Hollywood heavyweight." They were basically just two kids from the prairies trying to figure it out. When they moved to Toronto in 1982, Kim was working as a waiter at the Nags Head Tavern. He was chasing theater roles and probably smelling like stale beer and burgers most nights.
Diana was the one with the steady head on her shoulders. Kim has actually joked in interviews that, back then, she was the only one who could get a credit card. He couldn't get approved for anything. She was the financial backbone while he was auditioning for Macbeth and trying to convince people he wasn't just another guy with a cool face.

The Move from Saskatoon to Los Angeles
It wasn't an overnight jump to fame. After they got their degrees in 1981, Diana taught school in Kindersley for a bit. They lived that quiet, Canadian life before the pull of the stage became too much.
They’ve been living in Los Angeles for decades now, but they still feel very "un-Hollywood." They raised two daughters, Kyla and Brenna, in an environment that seemed to prioritize family over the red-carpet grind. You don't see Diana in the tabloids. You don't see them airing dirty laundry on social media. They just... exist.
A Partnership of Equals
Kim became a US citizen in 2010 (he keeps his Canadian citizenship too, obviously), and through every career shift—from Broadway to big-budget action movies—Diana has been the constant.
It's kinda rare to see a performer who is so high-octane on screen be so grounded off of it. He often credits his "girls"—Diana and his daughters—for keeping his feet on the ground. When he won the Best Actor award at the Canadian Screen Awards for Bad Blood, he wasn't just thanking a team of agents. He was looking at the people who were there when he was waitering in Toronto.

The Next Generation: Brenna and Kyla
The fruit doesn't fall far from the tree, at least in Brenna’s case. If you're a theater nerd, you might have caught Kim and his daughter Brenna Coates starring together in the play Jerusalem back in 2018.
Working with your kid can be a nightmare for some people, but for Kim, it was a career highlight. He talked about how surreal it was to look across the stage and see his own flesh and blood killing it in a professional production.
- Brenna Coates: Followed the acting path, earning her own stripes in the industry.
- Kyla Coates: Generally keeps a lower profile but remains a central part of the family unit.
Why Their Marriage Actually Works
So, how do Kim Coates and wife Diana stay together for four decades?
- They started from zero. There’s something about being broke together in Toronto that builds a bond fame can't break.
- Privacy as a priority. They don't overshare. You won't find 500 "couple goals" posts on their Instagram.
- Shared roots. Both coming from that Saskatchewan background gives them a shared language and set of values that Los Angeles hasn't been able to wash away.
It's easy to look at a guy like Kim—who plays these gritty, sometimes violent characters—and assume his life is chaotic. But the "Tig" persona is just a mask. At home, he’s the guy who’s been married to the same woman since 1984.

What We Can Learn From Them
If you're looking for the drama, you won't find it here. And maybe that's the point. The "actionable insight" here isn't some secret marriage trick; it's just about loyalty.

The reality of Kim Coates and wife Diana is a reminder that you can be a massive star and still have a normal, loving, decades-long marriage. It just takes a little bit of prairie grit and a wife who’s willing to let you use her credit card when you're a struggling waiter.
