Let’s make an Honor Roll for shuls that have a zero talking policy – nada, gornish, zilch, effes – during the time one arrives in shul until the end of davening.
I’ll start:
1) Emunas Yisroel – Harav Moshe Wolfson
2) Yeshiva Chaim Berlin
3) Lakewood Minyan of Flatbush – Harav Mordechai Marcus
4) Yeshiva Shaarei Torah – Harav Hillel David
Please feel free to add your own.
