I recommend Choi Won-jun Clinic in Jamsil.

These days, as the weather gets warmer, more people are visiting internal medicine clinics. I am writing to recommend Choi Won-jun Internal Medicine Clinic located in Jamsil. He is a renowned internal medicine specialist and gastroenterologist at Seoul Asan Medical Center. Additionally, he has the notable history of being the personal physician to the late Chairman Chung Ju-yung, which always attracts many patients. As a highly reputable hospital, it provides high-quality treatment that you can trust. Saturday consultations start at 8 a.m., which is even better.
