Have to say that we have not come across this particular company at all previously. Looking at their programme I have to say I have some concerns - it looks to be very US in approach (single sex sessions etc) rather than the more private and couple focussed approach of many of the organisations over here.
Their address is actually a firm of Chartered Accountants!
The cost is exorbitant (£1895 for a one night programme) compared with £200-400 for a typical weekend, or free if you choose Marriage Encounter!!
