I like the teacher at Tuntun Pediatrics on Jungang-ro, Jecheon-si.

This is a pediatric and adolescent clinic located in downtown Jecheon. It's easy to access because it's in the city. There's no parking facility in the building, but if you park in a nearby public parking lot, they'll give you a parking ticket. The doctor is very thorough and provides excellent treatment. There are always a lot of people, so the wait is long. It would be easier if you register first. There's always a long wait.
