I've got no problems with longer appointments, in fact I have quite a few regulars with longer appointments because they just don't find 1hr hands on enough (I won't do less, well I will because people ask for it, but 30min is priced only 10% less than 1hr, so most people will end up going for 1hr anyway).
Long appointments for the initial appointments seemed a bit much to me - many bodies will end up fighting back if you go for that long at that intensity initially. Which is why I'm interested in how many people offer this particular style and get rebookings. Many of the 'therapists' listed on the website seem to be B&B owners that probably got fed up trying to organise someone coming in and thought they'd do it themselves and went for a quick course. Are there professional practitioners just offering this style by name getting lots of repeat clients? Most of the raving comments seem to be by new graduates (as it is with most schools, the feedback form on the last day, how was your experience? is filled out with glowing comments, or at least only the glowing comments are referenced on the website, it's common sense) even the raving comments on message boards are along the lines of 'I just completed the course and found it amazing'. I'm interested how someone has found it in the long term, with more than one client a week.
Where I am, cases of fractured ribs happen every year, usually inexperienced therapists, but light 'holistic massage' training doesn't exist, basic qualification is sports/remedial/therapeutic style to be qualified, but you can put your shingle out as a massage therapist without any training if you want, you could even do one of these courses and put your shingle out.
