Elana!
It is Esther Levy.
I was really upside down when I saw the news. I would like to tell you about what I am trying to do here, at Stern, in the memory of Yochai Z"L. This Wednesday, I will try to have a Shiur dedicated to his memory. We are right now collecting funds for Magen David Adom, as a response to the repeated terrorist attacks; I will try to dedicate this money to Yochai's memory as well. Other than that, I got a lot of positive responses for the ambulance volunteer programs, and several stern students approached me with questions about this coming summer, I believe that more people joining this course would be the best honor to Yochai's memory, because it is exactly what he has always worked so hard for, and this what he has left to us, his students.
I am planning on publishing an article about him in the school newspaper, as well as local newspapers. I am also interested in joining another internship this summer with MDA Jerusalem. (when Yochai came to Stern, he told me about the Chovshim course and the bank hadam course, I am thinking of joining in)...
Tell me more about what I can do, send me material about Yochai and the program, I will do everything to be helpful. I would also like to get in touch with his family or send them a letter of comfort. If you could please provide me with more info and keep me up to date (I know you are good at that)
