Best private Healthcare (Medellin)

Hi guys,

do you have suggestions on which private Healthcare (as an addition to the EPS) is good for an expat in Medellin?
Things I look for is little waiting time for specialist appointments and proximity to the Southern part of town. Price is important in terms of value, not absolute.

Do you have good/bad experiences with the companies that offer this?

Thanks!

by the way Daniel: Well done for getting us our own group here!
