Dear Community Members, 


On behalf of Community Kashrus of Greater Philadelphia (Keystone-K), we wish a heartfelt Tzeischem L’shalom to Rabbi and Mrs. Eisemann who will be making Aliyah this coming May. Six years ago we engaged Rabbi Eisemann to fill the role of our first full-time Kashrus Administrator. During this time he worked tirelessly to assure the high standards of kashrus our community expects. Under his leadership, the Keystone-K continues to receive the respect and acceptance of all major kashrus agencies. Rabbi Eisemann’s other achievements include the expansion of establishments under our supervision to over fifty in number, employment of some of the latest technologies available for kashrus oversight, and the creation of a user-friendly website. Rabbi Eisemann has also left a lasting impact as a notable mechanech in our community.  For three  decades, he served as a Rebbe, teacher, and school administrator of Torah Academy of Greater Philadelphia and Kosloff Torah Academy Girls High School. Additionally, Rabbi Eisemann has played an important role as a local mikvah administrator and as a Mohel for many years.


We are excited to announce that Rabbi Yonah Gross will be assuming the position of Keystone-K Kashrus Administrator. Rabbi Gross has served as the Rabbi of Congregation Beth Hamedrosh in Wynnewood, PA for over ten years, and has been an active member of the rabbinical board of the Keystone-K for the last six years.  He has hands on training in kashrus through the Star-K, and over the years has developed a keen understanding of both the halachic and practical sides of kashrus. We are confident that these skills along with his familiarity with our community, will enable the Keystone-K to provide for the growing kashrus market of our region.


It is a great privilege for us to continue to serve the Greater Philadelphia community in providing the highest standard of reliable kashrus. We look forward to much success and growth in the years to come. 


Sincerely Yours,


Rabbi Dov Brisman

Rabbi Avraham Shmidman

Rabbi Mordechai Terebelo
