Rabbi Doniel Schreiber

Rabbi Doniel Schreiber has been a familiar and respected face at Yeshivat Har Etzion since way back in ’94. A proud graduate of the yeshiva himself (class of ‘86), he came full circle when he joined the faculty as a Ram—bringing his rich background in both halacha and Jewish history to the beis midrash.

He didn’t just stop at teaching. Rabbi Schreiber holds semicha from RIETS and earned an M.A. in Medieval Jewish History from Bernard Revel, which adds a strong historical layer to his shiurim. The result? A unique style of learning that connects the dots between the gemara, rishonim, and poskim—anchoring halachic discussions in clarity and conceptual depth.

In Alon Shevut, where he lives with his wife and their eight kids (kein yirbu), Rabbi Schreiber is more than just a neighborhood rebbi. He’s the founding dean of the Center for Torah Leadership at YHE, a program geared towards cultivating strong Torah voices for the next generation. And if you’ve been in Jerusalem on a weeknight, you may have caught his shiur—first at Kehillat Moriah, now going strong for years at the Hildesheimer Shul. His style? No fluff. Straight halachic lomdus with takeaways that stick.

But his influence goes way past the walls of a shiur room. Through the Israel Koschitzky Virtual Beit Midrash, Rabbi Schreiber authored a full online series on Hilchot Shabbat—making in-depth halacha accessible to a global audience. He’s also written for numerous Torah publications, and traveled abroad as a scholar-in-residence in places ranging from South Africa to suburban New Jersey.

One particular mitzvah that’s close to Rabbi Schreiber’s heart? Techeiles.

He wears it. He teaches about it. And he’s not shy about why.

Rabbi Schreiber follows the Rambam’s shitah when it comes to Techeiles—the elusive blue thread of the tzitzis that the Torah mentions but generations forgot. And while many still shy away from incorporating it, Rabbi Schreiber sees this as an area where halacha and historical research work hand in hand. His adoption of Techeiles isn’t just personal—it’s part of a broader movement within Yeshivat Har Etzion, where many rebbeim and talmidim have embraced this mitzvah as part of a renewed focus on practical, living halacha.

It fits with his overall approach: Halacha isn’t locked in the past. It breathes. It learns. It moves forward when approached seriously, with depth and intellectual honesty. That’s the kind of Torah Rabbi Schreiber lives and teaches every day.

If you’re curious to explore more of his work—whether it’s shiurim, articles, or his take on mitzvos like Techeiles—you’ll find a treasure trove of content on platforms like YUTorah and the Virtual Beit Midrash.
