In the Rio Grande Valley, stories of resilience and generosity are not uncommon. One such story belongs to Kristen Sandoval, whose life was forever shaped by her younger brother, Jaime “Jaimito” Longoria, and the powerful journey they shared through organ donation.
Jaimito was born with a serious congenital heart condition that placed him on the transplant list as a child. The months that followed were filled with uncertainty, countless hospital visits, and the kind of hope only families in crisis truly understand. Then, after a year-long wait, came the call that changed everything: a donor heart was available.
“His life completely changed,” Sandoval said. “He became a totally different person. You could just see it. It speaks to the magic of humans and how we are all connected.”
For the Longoria family, the transplant wasn’t just a medical event — it was a new chance at life. It gave Jaimito the opportunity to fully experience life and savor everyday moments.
Over the course of five years, Jaimito and his family made cherished memories that would endure forever. One day after commemorating the fifth anniversary of his transplant — and shortly after returning from a Make-A-Wish trip to Disney World — Jaimito sadly passed away.
“Unfortunately, the day after his five-year transplant anniversary, we lost him,” Sandoval said.
Despite the heartbreak, Jaimito’s story didn’t end there. In a final act of generosity, he became a tissue and eye donor, bringing hope and healing to others, just as he once received it himself.
“He finished out his story in the transplant world by being a donor,” said Sandoval.
Today, Sandoval serves as an advocate with Texas Organ Sharing Alliance (TOSA).
Having experienced both sides of the transplant journey — as the sister of a recipient and of a donor — she shares Jaimito’s story to raise awareness and inspire others to consider the lifesaving impact of organ and tissue donation.
“Organ donation allows grief to find a place to rest,” she shared.
Through her advocacy, Kristen honors Jaimito’s memory and encourages families to have open conversations about donation — something she believes can transform tragedy into purpose.
Jaimito’s legacy lives not only in the lives he helped save but in the hearts of those inspired by his story.
