One of Yitzchak Twersky’s great passions in life is teaching, or more accurately empowering people to enjoy the adventure of discovery and learning. He has taught students in a wide range of settings, formal and informal, reaching students younger than five and older than ninety-five, and everything in between. Some of the settings and media for this include his website and publications, online teaching, high schools, universities (Princeton, Columbia, Yeshiva University) and lectures in the United States, South Africa, Canada and Israel. In addition, Yitzchak has mentored teachers as department head in The Frisch School. He studied in Yeshiva University, receiving a Master’s Degree and two ordinations. Yitzchak lives in the Jerusalem area with his wife, Geula, who also teaches at OTA. He is the proud father of ten children and seven grandchildren.
