What Makes A Good Doctor?

What makes a good doctor... specifically, a good pediatrician? Is it the way she treats her patients? Is it the friendship that she builds with her patients' parents as well as their other family members? Is it the way she guides you on how to take care of your child during their "sick times"? Is it the many free medicine samples she gives you every time you come to her for your child's check-up? Is it about the discount she gives you from her PF?
