My colleague and I are in disagreement as to whether a comma goes both before and after the phrase or just before the phrase

Hi Guest,

Normally I don't put a comma when using as well as.

But I would have to look at the specific sentence in question before deciding. In other words, I don't know if you can provide a definitive answer to address all cases.

Back in the dark ages when I went to school, my English teacher taught us that commas go both before and after "as well as," but I am often corrected by my young colleagues for my abundant use of commas.
When in doubt, go without. That's a good general rule for comma use. Too many make it confusing.

I actually looked this up in one of my favorite grammar books - Woe is I. The example O'Conner gives is commaless.
