West Palm Beach, Florida (CNN) - Working as a guidance counselor five years ago in Palm Beach County, Estella Pyfrom noticed that fewer students had access to a computer after school.
The sluggish economy forced many families to prioritize their money and use it for more pressing needs.
"They needed food. They needed to pay their mortgage or their rent," said Pyfrom, a former teacher. "Some of them lost their cars. So I knew it was a serious problem."
Without a computer at home, or reliable transportation to get to a computer, Pyfrom feared that many of these students would get left behind.
So she bought a bus, filled it with computers and brought technology to the kids.
Her mobile computer lab, Estella's Brilliant Bus, has provided free, computer-based tutoring for more than 2,000 students since 2011.
"If people don't have some knowledge of technology, they're going to be limited," said Pyfrom, who retired in 2009 and used money from her savings to buy the bus. "It's absolutely essential that they get involved technologically."
