Demand is great, so Rolling Bay Presbyterian Church will host another Pop-Up Blood Donation Center Aug. 5-6.

The address is 11042 Sunrise Dr. NE, Bainbridge Island.

Make an appointment at schedule.RollingBay or www.BloodworksNW.org or call 1-800-398-7888, ext. 1.

Hospitals always are in need of blood donations during summer, but even more so this year as things open up after 1 1/2 years of COVID-19 restrictions.
