Seo is a 35‑year‑old professor of pediatrics at Soon Chun Hyang University Hospital. She has become a world‑champion boxer, showing how sport can help a busy doctor handle stress.

Seo began boxing in 2018 because she felt physically and mentally exhausted from her medical work. She cut her hospital hours so she could train five or six days a week.

On Oct. 17 2026 she won the Women’s International Boxing Association minimumweight world title. The win gave her a record of 11 wins, 1 loss and 3 draws. Before this, she held the Korea Boxing Commission’s national light‑flyweight title and the WBA Asian women’s minimumweight title, and she now aims for a major‑sanctioning‑body world title.

Seo says the physical and mental strength she gains in the ring helps her take better care of her patients. Her story shows that regular, disciplined exercise can improve mental health and work performance.
