In my honest opinion, Dario is one of the best deep tissue/sports massage providers on MF: https://www.masseurfinder.com/massage-therapists/15341/
He requires draping. I asked to remove draping and keep my briefs on, which he will accommodate. I stopped going to him as he does not handle business end of things very well and two instances were strike two for me and I am done. It's a shame because his kneading techniques are spot on. (feel free to PM for details)
I have read other users rave about Mike in Arlington although I have not been to him myself: https://www.masseurfinder.com/massage-therapists/43279/
I've not been to either of these therapeutic only masseurs (Chad & Ivo) but I have also read other users post good reviews about them on this forum
Chad: https://www.masseurfinder.com/massage-therapists/43883/
Ivo: https://www.masseurfinder.com/massage-therapists/10547/
If you do a search with the numeric value of their profiles (e.g., 43883 for Chad), you should see prior threads on them.
