There's no specific technique or process going on here to the best of my knowledge - the colours are fairly muted with a slight pink tint, that's all. What you're actually seeing is a set of very carefully prepared set of images by someone with a lot of experience.
There are a lot of "how do I achieve the post production of professional photographer X" questions on this site, and I don't mean to pick on this one in particular (indeed I think trying to imitate the work of photographers you admire is a great way of learning, and you certainly shouldn't be put off obtaining results like these) but I thought I'd try and prrpare a "catch all" answer to link back to.
Shots like these are the combination of a number of factors:
an experienced photographer ensuring maximum quality at the point of capture
a large sensor camera with fast lens
good quality soft lighting, no challenging high contrast backgrounds, hazy cloudy weather and the right time of day
consistency in colour correction. The actual corrections applied will vary considerably between images, but the point is the results are consistent.
tasteful restraint in post production, achieving a slick clean look and then stopping there
resizing and sharpening for the web
And finally
- only putting you best work forward. Cut ruthlessly and never let anyone see the ones that went wrong!
