Please recommend a dental clinic in Jongno area that specializes in orthodontics.

I had orthodontic treatment more than 10 years ago, and at that time, I went to a hospital introduced by someone I knew, so I received treatment in Ilsan, not Seoul. Since it was an introduction from someone I knew, I naively believed it would be cheaper and better, but I realized that was a mistake. Orthodontic treatment is not a one-time procedure; it can take 2-3 years or longer, and follow-up care is necessary. I regret having to travel almost every week or every 2-3 weeks to a distant place, which ended up costing more in transportation. It's better to get orthodontic treatment close to home. ㅠㅠ

I think it's time for our kids to get orthodontic treatment, so I want to consult about it. Is there a good orthodontic dental clinic in the Jongno area? The hospital where we go for cavity treatment doesn't do orthodontics. I thought about asking the doctor there, but... I believe those who have experienced it firsthand would know better, so I’m posting this question here for now~
