It was a reunion full of gratitude between a San Antonio transplant doctor and the man she donated a kidney to back in 2021.

Joel Gonzalez surprised Dr. Kelley Hitchman on Monday at her lab for what he called their fifth "kidney anniversary." KSAT has been reporting on the transplant pair for years now, including Hitchman's journey to climb to the top of Mount Kilimanjaro after the successful transplant to spread awareness about living donors and show people the healthy life a donor can still live.

KSAT also spoke with Gonzalez about how he is now thriving, and the importance of living donors.
