That does seem weird that the fitness center would call her? Or anyone for that matter other than you. My t has called me exactly twice - the first time, when I left a message requesting to make an initial appointment. And the 2nd time, because she realized she forgot to give me my receipt and to call back if I needed it sooner than the next appointment. And that was it. (I don't call her between sessions either unless I need to cancel/change an appointment.)
