Thank you in advance for wanting to donate blood for Jojo!  They will only transfuse A+ (his blood type) and he generally needs multiple transfusions of whole blood and platelets during chemo cycles and after surgery.  MSK will validate your parking up to 5 hours.  Please make an appointment at https://appointments.mskcc.org/blood-donor and select Directed Donation (see screenshot.)  Please reference Joseph Vizel.

 Please note that they cannot transfer donations from any other hospital or blood donation site.  It has to be done at 1250 1st Avenue in Manhattan.
