Does anyone have any opinions on Plumbers Success International? We currently run a primarily new construction company and would like to build our service business. We were approached by this company and attended their seminar. They are VERY expensive, but they do seem to offer a good starting point. I haven't been able to find any information on them other than what they have published themselves - which of course is all good. Does anyone have any real opinions on this company and if they are worth their steep price?
