Suggest Therapy For Stammering

Hello sir, I am Gobi, working as a manager for a big IT company. I have stammering from my childhoold, it was too bad earler and now it now manageable. I tried speech therapies and others treatments but of no use. I believe something happened in my childhood for this. Because I remember,till my 7th year (age) I was OK and after that it started. My question here is "is there any way to cure this by means of talking to mind using somepsycho treatment" ... ? Please help as I am managing around 60 people and my future career depends on my management which needs continuous talking.



Thanks.

Gobi
