On Wednesday, the city of Chattanooga hosted a blood drive.
Blood Assurance parked its bus right outside city hall, so employees could come down throughout the day to donate.
A spokesperson told us that Christmas is a slow time of year for them, so they're encouraging anyone who can.. to give blood over the holidays.
"The holidays really take people off focus of giving blood. They're giving to everybody else but they're not thinking about the blood supply," said Jay Baumgartner.
Blood Assurance hopes to help 75 people with Wednesday's donations.
Each donation can save up to 3 lives.
