Ask Dr. David Nguyen how he met retired Staff Sergeant David Harmon and he'll tell you they met at the gym, but it seems like fate played a big part too.
After getting to know each other during their workouts, the dentist from Houston, Texas invited Harmon to come to his clinic for a cleaning. But when the veteran opened his mouth, the dentist was stunned.
"I came in for a cleaning and he's like, 'My goodness!'" Harmon remembers. "And then I start telling him about all the pain I'm in."
While serving as a language instructor in the Air Force, Harmon suffered a number of accidents that left him with serious head trauma. That caused stress, insomnia, and memory loss so serious he would forget his wife's name.
But the most painful symptom was teeth grinding, which left Harmon with cracked teeth and infected gums.
Nguyen explained that repairing the damage would cost at least $15,000, but told his new friend he would give him a generous 70% discount. But when Harmon left the office, he told the receptionist he still couldn't afford his bill.
That's when Nguyen stepped in, and changed Harmon's life forever.
