Our mission on Friday, March 5th will be to Cornerstone Care in Greensboro, PA. Cornerstone Care serves a largely rural community of patients in an area that is known for coal mining and glassmaking. Our focus at Greensboro is detection of diabetic retinopathy. Our Greensboro mission will be followed the next day by a mission to neighboring Waynesburg. GES members who want to stay overnight will be fed and lodged courtesy of Southwest PA AHEC.
