Different opinions on this sentence

[Dom Aversano]

One person has told me this sentence is fine, another has said it is not.

I have been fortunate enough to have had the chance to learn from, and to befriend some of the greatest teachers and performers in the world.

Advice on this would be great, it is for a important letter.

Thanks

The sentence sounds fine to me.
Just a suggestion, 'chance' could be replaced with 'opportunity'.

Additionally, try dropping the comma:

I have been fortunate enough to have had the chance to learn from, and to befriend some of the greatest teachers and performers in the world.

Try,

I have been fortunate enough to have had the opportunity to learn from and to befriend some of the greatest teachers and performers in the world.

Thanks, I have already printed out many of the letters, so seeing as nothing is WRONG, I'm going to leave it how it is, although I can see your suggestions are valid.
