And while on the trip, Philipp received some good news from the admissions department.
"Coach (Jim) Harbaugh told me on Saturday that I had been accepted into Stanford. We were all pretty happy and my mom was really excited. She had told me to work hard and I would get accepted so it was pretty cool she was there to hear it with me," said Philipp.
That was the highlight but there were plenty of other enjoyable attributes of the visit. "I'd been up there before, but you get to see more on the official visit, so we did a bigger tour of the campus and of the facilities. Stanford is a really nice campus and there are a lot of really nice buildings there. It's a pretty big campus too so I got to see a lot more," said Philipp.
Philipp was hosted by Matt Masifilo and also spent time with Tavita Pritchard, plus the other numerous official visitors who were there over the weekend.
"I got to know a lot of the other guys on the visit, but some I had met before at camps and other junior days. I hung out with Levine Toilolo, Shayne Skov and Terrence Stephens a lot. I got to know some of the other players at Stanford too. We all really bonded," said Philipp.
But despite the news from Stanford of his admission, Philipp, who's played his recruitment close to the vest for a year, said he's not ready to name a favorite. "Getting into Stanford definitely helps me take them more into consideration, but I still have the same schools and one more visit left to take," said Philipp.
"I'll probably decide closer to Signing Day, and maybe on Signing Day," said Philipp. "I'm serious about all six schools and no school really has the lead."
Philipp visited Cal, Oregon and UCLA prior to the Stanford visit, and Arizona, where his brother Hans plays, has received a handful of unofficial visits.
"It's been a fun process and I haven't really gotten tired from it. I'll make the decision when I'm ready," said Philipp.
