Hello Elana,
Both Deena (my sister) and I became very close with Yochai during our trip to Israel last summer. I am devastated as I am sure you are - Yochai was kind, patient, and an excellent friend  - it is so hard to believe that it was just three weeks ago that I spoke to him about returning to Israel this upcoming summer!
I am currently in Ottawa, Canada in medical school, but on Friday, I will be returning home and Deena and I will put together some of the many pictures that we have with Yochai and send them to you.  Thank you for arranging this book and setting up the fund!!!!
Please let me know if there is anything I can do - I would be only too happy to help!
Thank you,
Karen Schiff
