After seeing a Facebook post from a mom desperate to find her 9-year-old son a kidney donor, Lindsey Bittorf couldn't get the message out of her head.
Bittorf, a police officer from Rock County, Wisconsin, and mother of a 2-year-old, decided to have her blood tested to see if she could donate her kidney to Jackson Arneson. It turned out she was a perfect match. Before the transplant in June, Bittorf became close to Arneson and his mom, Kristi Goll, and now, several months later, they continue to text daily. "I can't thank Lindsey enough," Goll told People. "She's one of the family now."
Arneson was born with posterior urethral valves, which usually causes kidney damage. Arneson is doing well post-transplant, and hopes to go back to school in a few weeks. "He is so strong and brave," Bittorf told People. "I am just in awe of him. He calls me his best friend now. It's amazing that we went from being complete strangers to best friends." Arneson said the kidney "is the very best gift I will ever receive. I'm going to take extra, extra good care of it."
