On the surface I would have thought Cleric with Healing Domain and Augmented Healing.
However, I just stated up a player's cohort and for ease of use I made a 12th level Favored Soul with Augmented Healing and Deity's Favor Alt class power from PHB II. I was shocked at how efficacious Deity's Favor will be.
For those of those that do not have PHB II, Deity's Favor replaces the Weapon Focus and Weapon Specialization class ability with the ability to instead add 3x the spell level in Temporary Hit points to the recipient of a spell, or to any amount of recipients at 12th level.
Thus a 12th level Favored Soul with Augmented Healing, casting a Cure Serious Wounds would heal 3d8 + 18 + 9 Temporary Hit Points.
That is a pretty substantial boost.
