Who Were Mark and Dena Glatt?
Mark Glatt, a respected California-based horse trainer, built his career over decades in the competitive racing scene. But behind his professional success stood Dena Glatt, his wife of 25 years and a cornerstone of their family.
The couple met in 1996 at Emerald Downs near Seattle. Dena worked as a waitress, and Mark had box seats. Their connection was instant, leading to a partnership rooted in love, family, and a shared passion for horses. Together, they raised three children—Ryan, Luke, and Madison—in Monrovia, California.
Dena wasn’t just a supportive spouse; she was actively involved in the racing community and deeply cherished by friends and family for her warmth and compassion.
The Sudden Loss: Dena Glatt’s Cause of Death
Dena Glatt died on February 12, 2026, at the age of 57. According to multiple reports, the cause was heart failure, also described as cardiac arrest following a short illness. She had been hospitalized for about two weeks at USC Arcadia Hospital before passing peacefully.
Her death came as a profound shock. Many who knew her described her as vibrant and relatively healthy, making the loss even harder to process. Heart failure can strike unexpectedly, even in younger individuals, often due to underlying conditions that may not show clear warning signs.
Key Facts About Dena Glatt’s Passing:

How Mark Glatt Is Coping and Honoring Her Memory
Grief hasn’t stopped Mark from moving forward, though every victory carries a bittersweet edge. So Happy’s win in the Santa Anita Derby—Glatt’s biggest achievement as a trainer—qualified the horse for the Kentucky Derby, but Dena wasn’t there to celebrate in person.
Mark has spoken openly about the emotional journey. He wears a bracelet containing some of Dena’s ashes so she remains close. In interviews, he shared a touching sentiment: “We’re still together, you know, even if it’s just in spirit.”
The racing community has rallied around the family, offering support during this difficult time. For Mark, the drive to succeed feels intertwined with honoring Dena’s memory—she was a big part of his professional life and his biggest cheerleader.
The Kentucky Derby Dream: Finding Hope Amid Heartbreak
As So Happy heads to Churchill Downs as a long-shot contender, the story transcends sports. It’s about resilience, love, and carrying forward the spirit of someone deeply missed. Mark’s first Kentucky Derby appearance comes at a time of immense personal loss, turning the race into a powerful tribute.
Fans and fellow trainers see this as more than a shot at racing glory—it’s a testament to human strength. Dena would undoubtedly be proud, roaring from the sidelines in spirit.
