Wilhelmina Holder, 68,
Executive Director, Women's Initiative for Self Empowerment
In 1985 -- five years after her father, the president of Liberia, was assassinated -- Holder, a doctor then facing threats to her own family, fled to Minnesota.
Lacking time and money to retrain for a license, Holder instead raised her four children, then in 2004 started a program to help other immigrant medical professionals get recertified.
The program has assisted 250 people from more than 50 countries; about 45 are medical residents or fully licensed. Holder also advocates locally and nationally for more residency slots for foreign-trained doctors.
"These educated medical professionals should be saving lives, not driving taxicabs," says Holder.
