LONDON (AP) — Must be a big taekwondo meet or something. Julio and Ondina Lopez are in town.

See, they don't often travel to watch their kids fight. Even now, after tons of national championships and world titles and Olympic medals, being around competitions is often too stressful for them.

This is different. It's the Olympics. No way the first family of taekwondo in the U.S. wouldn't all be together for this one.

Julio and Ondina's four kids all have roles in London. Steven Lopez will try for his third career Olympic gold. Some say 2008 women's bronze medalist Diana Lopez may be the world's best pound-for-pound taekwondo fighter. Mark Lopez is here as their training partner. And the oldest brother, Jean Lopez, coaches them all.

They're a family of Nicaraguan heritage, in a Korean sport, trying to bring more medals back to America.
