MPS Associates: Here to help

Associates are a group of MPS members who can provide peer support or are there if you need a medical colleague to talk to. They will treat everything in the strictest confidence and if you need medicolegal advice you will be referred to a specialist medicolegal adviser or one of our MPS panel lawyers. InCasebook we are allowing readers to get to know our Associates a little better – this issue covers Singapore.
