Is it best to stretch prior to a workout or after a workout?

I’m not fan of stretching (static). As for my clients if they wish to perform any type of stretching, I leave it up to them. For many years now I have followed this philosophy and I have never encountered any issues or problems because of it (same goes for my clients). There are different types of thoughts as far stretching goes and since the research on this topic it’s ongoing, I can’t say which one is better other than to rely on my own experience.
