Please recommend a good orthodontic dentist in the Jongno area.

I had orthodontic treatment over 10 years ago. At the time, I went to a clinic recommended by an acquaintance in Ilsan, not Seoul. I vaguely believed it would be cheaper and better because it was recommended by someone I knew, but it was a mistake. Braces aren't a one-time thing; they take two to three years, and you have to pay for aftercare. I regret having to travel to a distant clinic almost every week, or even every two to three weeks, and the transportation costs even more. It's better to get your braces closer to home. ㅠㅠ

I think my kids need braces, so I'd like to get some advice. Is there a good orthodontic clinic in the Jongno area? The clinic I go to for cavity treatment doesn't do braces. I thought about asking the doctor, but... I think someone who's actually done it would know better, so I'll post my question here first.
