It's the coaching staff that sold him on becoming a Beaver.
"Definitely Coach Riley and all the guys he's hired," he confirms. "They're great people. I like Corvallis also. It's kind of a lot like mine; it's a college town and I like that."
This past weekend, Vanderveen took his official visit to the school where he has verbally pledged.
"It was a lot of fun," the quarterback reports. "I just had a great time hanging out with the coaches. I liked the overall atmosphere and how the team interacted with each other watching the practice on Saturday and at the game."
However, the highlight of his trip didn't have anything to do with the coaches, the players, or the game.
Vanderveen's friend and teammate at Arroyo Grande, Garrett Weinreich, accompanied him on the trip. While on the visit, Weinreich made his own college choice.
"We were just hanging out in the players' lounge and he just said ‘I'm going to go do it right now.' It surprised me," Vanderveen recalls. "I was just really happy and I congratulated him."
"I'm really happy. Garret's a great player and he's a great lineman. I think it's going to be a great fit for him and I think that he has a great chance of playing when he gets there."
Weinreich's decision is one that Vanderveen has been awaiting for quite some time.
"Like every week, I would say something to him saying ‘Are you going to commit?' and bugging him," Vanderveen says of his part in recruiting his teammate to OSU. "I think it definitely played a role in making his decision having someone that he's comfortable with, so I think it helped a little bit."
The two have discussed their future in Corvallis.
"We're just excited and we can't wait to get up there and have fun," Vanderveen shares.
"I'm going to come in and get a chance to try to earn that starting spot. I want to try to start when I get there, but if that doesn't happen then I'll redshirt and just work on it and learn the offense."
On a scale of one to ten, Vanderveen claims he's a ten. The quarterback is all in.
"100% committed," he tells Scout.com.
