Kim siblings bring free tennis, hope to kids near contaminated Picher area

David Smale | May 06, 2026


If you’re concerned about the future of the U.S. when the next generation takes over, you needn’t be. Just look at Kate and Sejong Kim, a sister-and-brother combo in Joplin, Mo.

 

Kate is a Harvard tennis competitor, and Sejong is one of the top prep players in the state attending Joplin High School. They are using a passion for tennis and their concern for their fellow man to make a difference in their community and the communities around them.

 

Last fall, Kate saw a story in the local media about the disincorporated town of Picher, Okla., an abandoned town about 25 miles southwest of their hometown of Joplin. It broke her heart, and she decided to do something about it.

 

She founded the Enduring Scholars program, a nonprofit that has a purpose of providing “mentorships, resources and guidance to those affected by man-made or natural disasters in the Midwest states,” according to its website. Enduring Scholars is now a Community Tennis Association as well.

Contaminated Ground

 

Picher was once the site of a thriving lead- and zinc-mining industry. Beginning in 1917, the mines produced more than $20 billion in ore, including more than 50% of the lead and zinc used by the U.S. military in World War I. But when the mining stopped after World War II, much of the land left behind was contaminated with lead and zinc dust, which are known carcinogens.

 

The U.S. government spent billions of dollars cleaning up the area, but a tornado flattened the area and exposed much of the contaminants to the environment. Picher is now an abandoned community with no residents.

 

But young people from the surrounding area have started playing on the hills that are made entirely of contaminated dirt. They’ve even built dams to create swimming and fishing holes, bodies of water that are filled with contaminated water.

  

Kate saw the report about the area and decided to do something about it. She was joined almost immediately by Sejong. They were both concerned about the lack of concern for the safety of the area. They knew they needed to come up with another plan.

 

Safe Alternatives

 

Last fall, they started hosting tennis clinics every couple of months to draw attention to the situation. The clinics are free for participants. Racquets, balls and cones were all provided by Millennium Family Fitness in Joplin. The Kims have been pleasantly surprised with the attendance, which has averaged between 40 and 50 kids in the first four clinics.

 

A vast majority of the participants come from Joplin, though the plan in the near future is to partner with a nonprofit in Miami, Okla., which is about 10 miles south of Picher, to more directly help the kids that live in that area.

Besides giving the kids an alternative activity that is safer and healthier, there’s a secondary purpose of the clinics.

 

“An added bonus is spreading a love for tennis in our community,” Kate said. “Because I feel like, especially in small towns, it’s hard to get sports going sometimes.”

 

The clinics have two tracks, one for young kids and the other for older kids. The younger ones are taught how to hold and swing a racquet plus the fundamentals of the game. The older kids get more sport-specific training.

 

Next-Gen Impact

 

The Kims are well-qualified to lead the clinics. They’ve both been playing tennis for more than a decade. And they’ve been very successful.

 

They started playing when Kate was 10 and Sejong was 6. Kate is now a junior at Harvard, where she plays singles and doubles. Harvard won the Ivy League title last year for the first time in a long time.

 

Kate is a pre-med major looking forward to becoming a doctor. She has a health-centered approach to everything she does, including continuing to play tennis recreationally after college.

 

Sejong is a junior at Joplin High School, where he is one of the top prep players in Missouri. His goal is to study environmental science, possibly at Stanford or Harvard.

 

He’s going to work with the nonprofit in Miami this summer to see how he can help their efforts. No doubt he’ll spend plenty of time in Picher, convincing the young people there that there are better options than playing near contaminated water and soil.

 

While Kate and Sejong are both very successful tennis players, their future plans are to help others.

 

“We’re inspired by wanting to improve the public health of our community because of how toxic our local environment is and how many people we see with lead poisoning or even cancer,” Kate said.

 

“Obviously, we can’t help in any sort of medical sense because we’re not doctors. But we’re just trying to think of different, innovative solutions — any way that we can help.”

 

Nope, with young people like Kate and Sejong Kim coming along, there’s nothing to worry about.
