I have taught several friends including a 62 year old lady.
If he is athletic he should be fine but get a board with lifted up contact points and proper lessons.
My main suggestion is learn to ride somewhere there is powder, even if you take a 1 week trip somewhere.
Powder makes the difference between painful falls and possible injury and harmless, painless falls into a soft forgiving surface.
Its almost fun to fall on freshly groomed powder. Its hell on ice.
Keep in mind though that powder is something you learn after you get good at groomers... for beginner/intermediates powder is also some of the most frustrating stuff to ride because you have to be comfortable letting go and have good balance. Fresh groomers after it snows however are a lot more awesome to fall on.
