23. Pediatrician
Pediatricians certainly think their tiny clients are adorbs, but that’s not why they got into the kid’s medicine game. Pediatricians have gone through the same medical training as any other type of doctor, and they’re serious about their field. They do not exist to simply give vaccinations and tell you how healthy your child is; they also diagnose serious illnesses.
Pediatricians are a child’s first line of medical defense. They get involved early in life, and they help set a child up to become a healthy adult. These days, they see patients as old as 21. Patients might be slightly less cute at that age, but pediatricians don’t seem to mind because the brain is still developing.
