So what I could find is that after his days at BYU he worked in real estate and started a WR training program called Miles_WR. could only find an instagram account:
Ross Apo is a private WR Coach. He has not joined the Utah staff in any way shape or form. He has garnered a good reputation as a private WR Coach and makes more money as such which is why he has not joined any coaching staff anywhere
He has a bone to pick with byu because they haven’t recruited some of the kids he’s coached. He has sent them info on some good prospects and they have told him no thanks.
