I recommend Jamsil YB Pediatrics and Adolescent Clinic.

Hello. Raising a child requires frequent visits to the pediatrician. While there aren't many pediatricians, the options are limited, but I highly recommend YB Pediatrics and Adolescent Clinic in Jamsil-dong. They're open until 1 p.m. on Sundays and public holidays, except Thursdays, which is incredibly helpful. My regular clinic closed, so I went for the first time, and the director is incredibly thorough and attentive. I've recommended them to many people around me. I used to have to scramble to get there on holidays, but thanks to them, my child is growing up healthy.
