The Tikkun Olam Committee hosts its annual blood drive on Sunday, March 8th, and this year we're trying something a little different. The Mass General Blood Donor Center will park a self-contained, state-of-the-art Bloodmobile in the Ambrose School lot from 8:30 am to 2pm. Schedule a time and do a mitzvah by signing up online at http://bit.ly/Shir-Tikvah (preferred method.) Or contact Kim Cronin at the MGH Blood Donor Center at kcronin@partners.org or 617-726-8165. Each year, thousands of lives are saved by the simple, selfless act of giving blood. Patients in need include those with cancer, sickle cell disease, as well as accident victims.
