Dr "Harry" Harris shared a touching Facebook post as he returned home after the miracle operation that involved experts from 13 countries across the world.
Her words are likely to give comfort to the 12 boys who were last seen in a recent video that showed them recovering in isolation at the Chiang Rai Prachanukroh hospital after more than two weeks underground.
And an Ohio State University graduate played a key role in the team's successful rescue.
Master Sergeant Derek Anderson, a rescue specialist with the US Air Force, told the Associated Press divers practiced their action plan in a swimming pool on local children that were about the same height and weight as the boys inside the cave.
They were brought out safely following an extraordinary saga of worldwide cooperation and ingenuity, as experts from many fields planned how to manoeuvre all 13 out alive.

Local military, police, and the Thai Navy SEALs worked alongside thousands of local and global volunteers, divers, doctors, and experts to aid in the urgent rescue mission. "But it's really the worldwide team I would like to focus on and the Thai SEALs".
"We were very relieved that they were all alive but I think at that point we realised the enormity of the situation and that's perhaps why it took a while to get them all out".
"I want to tell the boys, please don't blame yourselves", Valeepoan Kunan said, as reported by Reuters.
