SHERMAN, Texas (KTEN) — This month, the Texoma Heroes program celebrates 10 years honoring veterans, and Mark Kosemund is the latest to be recognized.

"The military is not just war," Kosemund said. 

Kosemund served in the United States Marine Corps from 2003 to 2007.

"I wish more people would choose to serve in the military, because you get to leave your bubble," he said. "You don't stay in your home town; you get to experience different cultures, food, language... everything else."

After serving in various law enforcement capacities, he joined the Grayson County Sheriff's Office in 2019 as a patrol deputy. He was promoted to patrol lieutenant in August.

Kosemund said he joined the Marines to follow in his family's footsteps. He was humbled to be named a Texoma Hero.

"To be counted among this group... I mean, read some of their bios," he said. "I read mine, and it pales in comparison. Some of the guys that are Vietnam vets with three tours, and I look at me, and I'm not a hero."

Throughout his career, Kosemund has dedicated time to promote mental health awareness within law enforcement.

"Law enforcement has kind of been left behind over the years," he said. "For a while in Texas, I think Texas was leading the nation in law enforcement suicides, and first responder suicides is an extension of that, and we have to find a way to stop it."

Sheriff Tom Watt nominated Kosemund for the Texoma Hero recognition. Watt said the day Kosemund joined the sheriff's office was "a great day."

"I had no idea what kind of an asset we were bringing on board, but there's not anything he's not willing to tackle, and everything he tackles he succeeds at," Watt said.
