This was mid '90s when they were just flat out dominant. His coaches were the wrestlers themselves, but they included multiple national champions and all-Americans. He said that the organization and setup was incredible. Morning conditioning sessions, roughly 6 hours a day on the wrestling mats, and nightly activities/classes that included the sports medicine department conducting body fat testing, classes on nutrition, and talks from Dan Gable who had just retired as coach (and who I didn't even know about until then) and other visiting olympians.
He said the camp was attended by numerous ranked high school wrestlers, many of whom he looked up and were wrestling for well known D1 programs. Ironically, none of the ones he knew ended up going to Iowa even though he said some of them were good enough to go. Sounded like an incredible experience.
