where to put the comma between two distinct quote?

Where should I put the comma and the quotes in such a sentence?

The comments were significantly focused on my being “engaging, patient and extremely helpful,” “very coherent and easy-to-understand,” or "clear and straight to the point".

My question is whether I can do something like this "bla," "bla" - meaning, a simple space between two quotes and the comma before the first one.

Thanks!
