I learned about IFS after I had gotten out of rehab. It's definitely not something every therapist will know a lot about or be willing to practice. It seems like the ones that do work IFS into therapy are ones that are like super trauma-informed. In reading about it on my own, I didn't see how it made much sense, but then I briefly saw a therapist that was really heavy into practicing it and had HUGE lightbulb moments while we talked it through and how it applied to me. The overall concept makes a ton of sense, although I did feel weird naming my "parts" (firefigher, exiler, etc). We didn't click so I didn't see him for very long, but I can see why its an attractive therapy model, especially if you have complex traumas.
