LEWISTON, Maine (NEWS CENTER) -- One of our Teens Who Care award winners from 2007 is graduating from Bates College Sunday, and he hasn't stopped helping others.
Chomba Kaluba grew up in Zambia and came to this country when two peace corps volunteers helped him become a student at Southern Maine Community College.
He then moved on to Bates, and continued travelling around the world.
He worked with efforts to eradicate HIV/AIDS in Tanzania, Kenya, Zambia and South Africa. He then went to Guatamala with the Maine-based group Safe Passage, helping families who work at the garbage dumps.
