WMI Team


Rabbi Matan Mordechai Weisberg

Director Heritage House and programs

Raised in South Africa and Israel, Matan is fluent in Hebrew and English. After graduating high school, Matan joined the IDF’s MLRS unit for 3 years. During those years his interest in understanding Judaism was sparked. This led to many years of serious religious and secular Jewish education. Matan’s passion for enabling young Jews to be exposed to their rich heritage propelled him to undertake continuing Rabbi Meir Schuster’s Heritage House from 2011. If you want to get on his good side, ask him an extremely tough Judaism question which will make him have to think for a couple days.


Chaya Weisberg, Co

Director Heritage House and programs

Chaya, originating from the east and west coast of the US, has been with the Heritage House since 2004. She brings people wisdom with a MSc in Sociology from U. of N. Texas, and an infectious love for each individual. Chaya and her family enjoy sharing their balcony view of the Western Wall with Birthright and Heritage House students, especially if they sing a Jerusalem song. When you come to visit, prepare a song and ask for some hearty soup, and be welcomed into the family!


Chassia Thau

WMI program director

Chassia grew up in Israel. After studying Education and Business she spent some time working in the non-profit sector as well as teaching. Chassia is currently the director of Way More Israel, and loves every part of it! Developing the program, meeting the participants, and sharing what Israel has to offer are just some of the perks.
