( sorrys about the wrong info about the interrruption ) and high school you just got to find the right friends I think and people who dont care about the stutter ( im only in freshman year ) and my stutter aint very bad but I still get made fun of everynow and then for me at least its just having to power through it ( im also a very social kid so I am ok with talking in front of crowds ( even with the stutter ( idk how i do it ) ) ) but as long as he can get some friends and people ( prefrable other kids ) that will stand up for him that should help ( others dont tease me about my stutter much but I do know my friends will stand up for me if they do ) and I am trying to help but my advice probaly aint the best just because mine isnt as bad as some ive seen but onething that does help a lot ( i refuse to do it tho lol ) is like if i start to stutter stop what im saying say it in my head then say it outloud helps
