Grammar, Usage / Did I put the comma's in the right place in this sentence?! [6]

I think the commas in the first sentence are OK. It just depends on how pronounced you want the phrase "in addition to academics" to be. I could read that phrase without it being separated by commas.

About the latter part of the sentence, I would put a comma between "community" and "and" in "to one's community, and I believe".

That's my editorial opinion. Thanks!
