Our country has experienced too many national disasters in a short period of time — three catastrophic hurricanes and the horrific shooting in Las Vegas — and blood supplies are precariously low. Donations maybe made at the Melville Donation, 905 Walt Whitman Road, Melville, or during local blood drives. To make an appointment and find out about community blood drives call the Donation Center at 800-933-2566, or visit online at nybloodcenter.org.
