I stay in the area but i usually head to HV for my massages. Never heard of any good places around here.
There's a clean massage outlet along the same roll as the banks at HV (above OCBC) that does good foot and body massage. There are also a couple of TCM massages around wala wala i've tried that offers pretty good firm massages.
But let me know if you find good ones near ghim moh
