NORTH FORSYTH — Red was the color of the day Thursday at the Forsyth County Senior Center. Realtors and office staff of Keller Williams Realty Community Partners, along with several of their vendors, spent the day volunteering at the Center at Charles Place, next door to the Cumming Library. The help of about 50 volunteers was offered through Keller Williams’ annual RED Day, in which employees of the organization fan out in their communities around the world for a day of service.
