It's called Yonsei Bright ENT Clinic (formerly Haemaeul ENT Clinic), so it appears on your credit card receipt as Haemaeul ENT Clinic. The director, Dr. Cho Seong-yeol, is an ENT specialist who graduated from Yonsei University College of Medicine and has been practicing in the Shintanjin area for a long time. He meticulously examines the condition of the ears, nose, and throat using an endoscope and directly shows and explains the treatment to patients for ENT conditions such as rhinitis, sinusitis, otitis media, otitis externa, pharyngitis, tonsillitis, dizziness, and tinnitus, which makes me trust him even more. Since he is famous for his skills, there is a lot of waiting time on weekday mornings and Saturdays. I recommend visiting with plenty of time.
