Rabbi Jason Wiener is a young rov who has done an outstanding job as the senior Jewish chaplain at Cedars-Sinai Hospital Center in Los Angeles. His penchant for serious treatment of halacha is obvious in the great public service he has performed by putting together an extremely useful chibur on issues relating to hospital stays. This monograph was supervised and looked over by some of the most impressive names in psak halacha in Los Angeles. It includes the single best treatment of the use of elevators on Shabbos that I recall seeing.
