I've seen Mac. He's not Russian. He's an American boy from Phoenix and looks exactly like his pictures. My experiences with him have been good, including his massage. I think @hgpal is right that Mac has no formal training. In our first session I told him how I like to be massaged and he seemed interested in learning. He remembered what I like and has done some fine tuning at subsequent sessions. I'm happy with his work and I like him. When Mac works on me he sets a timer. I'm really sorry about @hgpal's bad experience... For what it's worth, I'm 70, white, chubby, mostly in it for the massage.
