Is there a way to combine text from multiple cells into one cell with a comma b/t?

Hi All,

Is there a formula or function in excel that would allow me to combine text from several cells into one cell with a comma in between the text?

So cell B2 says "He does well" and C2 says "Strong worker" and D2 says nothing, and E2 says "Doing Okay"

I would like that combined into A2 to look like this - "He does well, Strong worker, Doing Okay"

I believe I can do this "=B2&", "&C2" but I how do I do it for more cells? Also is there a way to ignore blank cells so there won't be a blank comma?

Please let me know. You all have been great so far. Thanks!!!!!!
