"This is a great group to work with," says van Asten. "Since I've been here we've always had a really, really good group. There's a spectrum for sure. If Mark Giordano's on one end, there's someone else on the other end. But the training culture here, since before I arrived, you could tell was really strong. I have no complaints."
NHLers, of course, are highly-paid professionals trying to parlay a relatively short career life into the most, both competitively and financially.
Therefore, unshakable belief in the advice or information you're being given is nothing short of paramount.
"Trust," agrees van Asten, "can be the biggest component. At the end of the day, you could have the greatest nutrition program but if the players don't trust you and don't do what you're recommending, it's not going to work anyway.
"We have an open-door policy. Have a question? Ask. I'm certainly open to suggestions. If someone like Gio, for instance, with his experience in the league and attention to this side of it, wants to discuss something, I'm all ears.
"And the reality we all have to understand is, everyone's different. So you have to look at the individual. What might be appropriate for one guy, isn't for another.
"Not that long ago, the blanket-type thinking was: Everybody needs to be doing this, this and this. No variance. This is the program.
"Nowadays, we do things like monitor blood level, for vitamins, minerals and hormones and say: 'OK, this guy is deficient in vitamin D so we need to increase his intake of that.' Whereas others might be deficient in X, Y or Z.
"You do, in a sense, have to customize the programs for each player."
