The 19-year-old's announcement went well beyond the hockey world, with Rock & Roll Hall of Famer Elton John calling Prokop the day after he came out.
"We just had a really good conversation," Prokop said. "He congratulated me, just asked me how the day was, how the support was, and then he thanked me for being brave and coming out. It was a really cool conversation."
Prokop said he also has gotten great insight from Brock McGillis, a former Ontario Hockey League and semiprofessional goalie who came out as gay in November 2016.
"I'd spoken a lot with Brock McGillis throughout my whole process of coming out, and he was really good in lending me some advice to do with media, what's going to happen the day of, the day after, the month after, year after," Prokop said. "He's just a really good source I have, and a friend, I'll say, as well. We're in touch daily, so I'm very thankful to have him as well."
