Mark Casse is everywhere. If you’ve spent five minutes looking at a racing program from Woodbine to Gulfstream, you’ve seen the name. Honestly, it’s easy to just view him as another "super trainer" with a massive stable and a fleet of assistants. But that’s a mistake.
Basically, people think Casse is just a volume shooter. They see the 4,000 career wins—a milestone he hit in July 2025 with a filly named It’s Witchcraft at Colonial Downs—and they assume it’s just a numbers game. It isn't.
He's a guy who started mucking stalls in Indiana winters and ended up in two different Halls of Fame.
The 4,000-Win Milestone and the 2026 Surge
We are only a few weeks into 2026, and Casse is already putting on a clinic.
Look at Oaklawn Park right now. He just tore through their holiday meet with a 48% win rate. Think about that. Nearly half the horses he vanned into Hot Springs, Arkansas, came back with a winner's circle photo. He won the Smarty Jones Stakes on January 3rd with Strategic Risk, a homebred for John Oxley. He didn't just win it; he ran first and second.
It’s a "stable exacta" that makes the game look easy, but it’s actually the result of a very specific, very complex ecosystem.
Casse is currently vanning his "A-team" into Oaklawn in waves. We're talking about Grade 1 winners like Sandman and La Cara. Then there’s Nitrogen, the Alabama Stakes winner who is a finalist for an Eclipse Award. She just arrived in Arkansas to prep for the Apple Blossom. This isn't just a trainer; it’s a logistics empire.

Why the "Canadian Trainer" Label is Misleading
Most fans outside of Toronto still think of Casse primarily as the king of Woodbine. Sure, he’s won 17 training titles there. He has a record 16 Sovereign Awards as Canada’s Outstanding Trainer. But calling him a Canadian trainer is like calling Secretariat a "decent horse."
He’s an American, born in Indianapolis in 1961. He grew up in the dirt of Ocala, Florida. His father, Norman Casse, was a titan who helped start the Ocala Breeders’ Sales (OBS).
Mark was running his dad’s training operation at 15. Imagine that. Most of us were struggling with geometry, and he was managing Thoroughbreds. He got his license at 17.
The move to Canada in the late 90s was a business pivot. He saw an opportunity at Woodbine and took it. But his operation is actually a massive triangle:
- The Farm: Moonshadow Farm in Ocala, where horses get their "early education."
- The North: Woodbine, where he dominates the synthetic and turf scenes.
- The South/Midwest: Major strings at Churchill Downs, Keeneland, Saratoga, and now a powerhouse division at Oaklawn.
The Tepin Factor and the Synthetic Debate
If you want to understand why Casse is different, you have to look at Tepin. She was the "Queen of the Turf." In 2016, Casse took her to Royal Ascot to run in the Queen Anne Stakes.
No Lasix. No nasal strips. In a driving rain on a straight course she’d never seen.

She won.
That victory changed the way American trainers were viewed globally. It also solidified Casse’s reputation as a master of the grass.
He’s also one of the loudest voices in the room when it comes to synthetic surfaces. While some "old school" guys hate Tapeta or Polytrack, Casse argues that it keeps horses sounder. He’s famously quoted as saying that while 80% of horses like turf or synthetic, only about 30% actually enjoy the "cuppy" kickback of a dirt track.
The Family Business and the Future
It hasn't all been roses. His son, Norm Casse, was his right-hand man for years before going out on his own in 2018. That’s a big hole to fill in a company that employs over 200 people.
But Mark just keeps "steering the ship," as he puts it. He’s got assistants like Caden Arthur handling the Arkansas string and Nick Tomlinson in the trenches at other tracks.
He’s also become a bit of a political activist lately. In 2025, he was at the forefront of the fight against "decoupling" in Florida—a move that would let tracks keep slot machines without holding live races. He argued it would be an "economic disaster" for Ocala.

He isn't just training horses for the winner's circle; he’s trying to save the ground they run on.
What You Should Watch Next
If you are following the 2026 racing season, you need to keep your eyes on the Casse barn.
Pay attention to these specific names and trends:
- Strategic Risk: After that Smarty Jones win, he’s a legitimate Kentucky Derby contender. He’s by Noble Bird, a horse Casse actually trained, which shows the "full circle" nature of his operation.
- Nitrogen: Watch her in the Azeri Stakes on March 7th. If she wins that, she’s the heavy favorite for the Apple Blossom and could secure an Eclipse Award for the Casse mantle.
- The 5,000-Win Chase: He joked that he’d retire at 5,000 wins, then changed it to 6,000. At the rate he’s winning in 2026, he’ll be closing in on that sooner than his wife, Tina, probably expects.
Keep an eye on the "waves" of horses moving from Ocala to the major tracks. When Casse ships a horse that has been prepped at his own training center in Florida, they often win first time out. That’s where the real betting value is hidden.
Don't just bet the name; look for the "Casse-trained, Ocala-prepped" pattern. It’s been the blueprint for 4,000 wins and counting.
