Sofia Manfredi, a Brooklyn teen, is getting a new kidney this week thanks to an online kidney matchmaker and a New Jersey teacher.

With severe damage to both kidneys from complications during her birth, 13-year old Sofia has been relying on medication throughout her life. Now, her undersized kidneys are unable to cope with her growing body.

Last summer, the Manfredi family sought the help of Chaya Lipschutz, who runs an online kidney matchmaking agency, SaveALife-DonateAKidney.com. When she sent out an alert, she immediately got a response from Cherry Hill teacher Jennifer Rothstein, 39, who volunteered to donate one of her kidneys. After a few months of tests, doctors found Rothstein to be a perfect match for Sofia. The transplant surgery is scheduled for this coming Tuesday at New York Presbyterian Hospital.

“It just felt like it was the right thing to do,” Rothstein said. “I was blessed with good health. There was no reason not to.”

“I feel like I won the lottery,” Rothstein added. “It’s like giving birth. It’s giving life.”

Sofia’s mom, Tami Manfredi, said “It’s amazing that someone I’d never met before could be so giving. She is giving my daughter a second chance.”
