Before Dierks Bentley’s concert at the Save Mart Center in Fresno, Calif., on April 29, he helped one soldier—Staff Sergeant Steven Mendez—and his family create an unforgettable memory.

As the soldier’s two sons were taking pictures and chatting with Dierks backstage before the concert, SSgt. Mendez, who had been overseas for 10 months, casually walked into the photo opportunity. SSgt. Mendez’s sons were so stunned that it took them a few seconds to regain their composure and embrace their father.

Later that evening during the concert, an emotional Dierks invited the Mendez family onstage and thanked Steven for his service as the crowd chanted “U.S.A.”
