One of the disorder for which this kind of quack you will get are stammering.They will tell abut themselves I went for speech therapy but it did not work and than I develeped my own technique to treat stammering.As they have already consulted speech therapist so they learnt the few techniques from speech therapist and with some modification or some time similarly use for other people with stammering.As such quack are not success in their profession so they switch to quack practice for money making.First experience I got when I was studying at AIIMS Delhi after that so many clients came to me when I started practicing at Bangalore. Many people came and told that how they were cheated by such quack for their stammering cure who took 100% guarantee for stammering cure also but truth was different .They will claim their center is only capable 100% treatment of stammering only in India.
