'He's my superhero': Tennis player Marek Dessimoz saves woman from fire

David Smale | July 21, 2026


Marek Dessimoz, a member of the boys’ tennis team at Dowling Catholic High School, enjoys watching Marvel movies with his dad, but he considers them all fantasy. He says there’s no such thing as a superhero.

 

His mom would beg to differ.

 

Dessimoz was playing golf with his parents in the Des Moines suburb of Johnston, Iowa, this past Mother’s Day when they noticed the deck of a house across the street from the course was on fire. Dessimoz and his dad jumped the fence that bordered the golf course to see if they could figure out whether anyone was home.

 

While his dad went to the back of the house Dessimoz went to the front, where he peered through a window to see the homeowner. He pounded on the window, and the panicking woman opened the door and let him in.

 

Dessimoz and an Amazon driver, who happened to be in the neighborhood, convinced the woman to come out of the home just before a propane tank exploded. The flames spread from mostly on the back deck to the upper level of the house, including the roof. The house was totally engulfed in flames.

The woman then remembered her cat was inside and rushed back in, but Dessimoz and the driver brought her back out. The woman’s cat was later found — alive — in the house’s basement after the fire was extinguished.

 

Many people, including Dessimoz’s mother, Agnieszka Pieta, called him a hero for stepping up in a time of crisis.

 

“He’s my superhero,” Pieta told a local television station in Des Moines. “It’s the best Mother’s Day gift he can give.”

 

Dessimoz, who is about to begin his senior year at Dowling Catholic High School in West Des Moines, said he just did what needed to be done.

 

“I don’t consider myself a hero,” he said. “I saw how big it got; it was spreading on the walls. I just did what I thought was right.”

Marek Dessimoz (far right) is a standout player on the Dowling Catholic High School boys' tennis team. He helped save a woman from a house fire this past Mother's Day.

Dessimoz’s mother wasn’t the only person impressed with the high schooler’s actions.

 

“Getting her out in a timely manner was certainly key,” said Percy Coleman, fire chief of Johnston-Grimes. “I think it’s safe to say it really saved her life here.”

 

Dessimoz doesn’t limit his heroics to saving people from house fires. He helped Dowling Catholic reach the Iowa Class 2A state quarterfinals as a junior, playing both singles and doubles. Dessimoz also competes in USTA Iowa junior events.

 

He has played tennis for five years and has been a varsity tennis player for Dowling Catholic since his freshman year. Dessimoz has helped the Maroons qualify for state twice. He has qualified for the individual state championships in doubles his sophomore and junior years.

 

Dessimoz is looking forward to his senior year, where he hopes the Maroons can go a step or two farther in the state playoffs.

 

If he can do that, who knows what his mom might say about him.
