By Christine Rousselle, CNA/EWTN News - Three years ago, a medical office in Manassas, Virginia was one of the area’s largest abortion clinics. Today, it is a free medical clinic for the poor, dedicated to the Blessed Virgin Mary... The Mother of Mercy Free Medical Clinic opened its doors on Dec. 6, 2017. Supported by the Catholic Charities of the Diocese of Arlington (CCDA), the clinic provides free medical care to uninsured or underinsured adults living in Northern Virginia.
