HaRav Zecharia Senter, ZT”L

It is with profound sadness that we take note of the פטירה of HaRav Zecharia Senter, ZT”L, head of the Kof-K.

In addition to being a prodigious תלמיד חכם, Rabbi Senter founded and led the Kof-K since its inception all these many decades.  While still a young student at Yeshiva Rabbi Yitzchak Elchonan, Rabbi Senter had started an independent source of inquiries and information on kosher matters. This “hobby” developed into an international kashrus agency renowned for its dedication to the highest standards in kashrus enforcement.
