Best places that do deep tissue massage?

My sister lives in Boise and is really struggling with severe tinnitus. I’d love to get her a certificate somewhere for a place that does deep tissue massage. Does anyone have suggestions?

Not looking for a place where you feel like someone beat you up the next day, but she really does not like places that do more soft-touch stroking type of massage. Looking for more “a bit painful but also feels great” deep tissue massage.

Thanks!!
