I agree with one caveat. The best assistants I have worked with over the years seem to have only been helping one provider, at a time at least. They were truly assistants, not pimps or agencies (though agencies have their own place in the community). Their purpose seemed very clear and was nothing more than being available to communicate when the provider wasn't. This made scheduling a lot easier.  Ladies understandably are not on their phones when in appointments and have other things like hair, nails, lashes, gym, etc plus family and personal life that can make them hard to catch when I would have a window. I think most men, like myself before I retired, have limited chances to communicate in order to remain discreet. When there is an assistant who I know I can text anytime and get a prompt response allowed me to schedule a lot more often. Like ALOT more often, ie. twice a week vs once a month. I think everybody came out ahead in those situations.
