For those not taking part in the Case for Community Day events, you can still get involved by donating blood for the American Red Cross of Greater Cleveland at Thwing Center’s 1914 Lounge, Nord Hall 310 or 121 Fitness Center. All volunteers must register online before donating blood. Appointments are available from 11 a.m. to 5 p.m. at all three sites. Click here to find an appointment time and to register.
