For Dahlonega resident Marisa Pyle and her family, the Affordable Care Act has been a lifesaver. This past year, she was diagnosed with two autoimmune disorders, and “the medication and care for them and my ability to continue college is dependent on our insurance through the ACA,” she said. And that’s what drove her to speak out Monday morning at a protest in front of U.S. Rep. Doug Collins’ Gainesville office, where about 100 sign-carrying, chanting protesters called for, among other things, Congress preserving the Affordable Care Act.
