At age two, Jini’s brother Kimong was diagnosed with severe autism. By age eight, he developed grand mal seizures. He hit his head when he was frustrated, flapped his arms when he was excited, and learned only three words: eomma (mom), appa (dad), and nuna (big sister).

As recent immigrants from South Korea, Jini and Kimong’s parents were unable to confidently speak or read English. Their family struggled to keep up with mounting medical bills. In 1990, at age nine, Jini helped to enroll Kimong in Medicaid, protecting her family from debilitating debt.

Fixing American healthcare became Jini’s life’s work, and when she founded her own company, she named it Nuna in honor of Kimong, caregivers, and big sisters everywhere.
