If you need to immediately consult with a Rabbi before making a decision concerning an actual case of organ donation then this is considered a medical emergency because you can save 8 lives.
First, try to contact Robby Berman by doing the following three things:
(1) Call his U.S. cell phone number at: +1-646-645-4637
(2) Send him an email at: email@example.com
(3) Call his cell phone number in Israel at: 011-972-52-527-5284 (from the US) or +972-52-527-5284 (from outside the US) or 052-527-5284 (from within Israel).
In addition, the following Orthodox Rabbis have agreed to be contacted. Please note: If you are calling the Rabbi on Shabbat or a Jewish Holiday, since this is a life saving matter the Rabbis are willing to answer your call. You may need to call their phone numbers repeatedly so the Rabbi knows this is a medical emergency and he will eventually answer the phone. Please start by calling the Rabbis that are geographically closest to you (country, state, and city).

Rabbi Polak writes: “If it’s Shabbos or Chag, I live within walking distance of most major hospitals in the Boston medical area, and I can be contacted by someone tapping on my front window to the left of my entrance at 61 Longwood Ave.”
