They're going door to door across the state as part of a nationwide effort to reach out to both the uninsured and the under-insured.
"We're a non-profit organization that's getting the word out on the health exchange marketplace opening on Oct. 1," said Shalyn Shanks, a Get Covered America volunteer.
Come next month, Americans will be able to go online and shop for health care coverage in the federal insurance marketplace. There, they can compare prices and browse through different insurance companies.
"We know about 78 percent of consumers that don't have insurance don't even know about ACA, don't even know they could get health insurance under the new law, don't even know they could get help paying for that insurance under the new law," Gammill said.
As volunteers cross the state, they're doing so in pre-selected precincts.
"We've identified neighborhoods throughout Texas and, of course, here in Austin that have a high number of uninsured people," Gammill said.
The Texas Medical Association has pegged the state "the uninsured capital of the United States,” with more than 6.3 million people lacking in health insurance.
There is still a big push by some Republicans on Capitol Hill to defund the program. They argue the Federal Government shouldn't require people to be insured, and that it'll cost many businesses and taxpayers more money.
