Amy Goldman

Gimel Hebrew, Vav Judaics, Hay Hebrew

Amy joined our teaching staff in 2020 and has extensive experience in Jewish education. Amy loves the creative arts and cooking--two passions that she’s already brought to her students at Mishkan!

Cantor David Acker

Hay Judaics, Vav Hebrew

David holds a Masters in Cantorial Studies and Jewish Music from Gratz College as well as music degrees from Temple University’s Esther Boyer College of Music and Swarthmore College. He is also a candidate for a Masters in Jewish Education at Gratz College. David challenges his students to invest their own creativity, imaginations and intelligence into the development of their Jewish identity. Through experiential learning, he facilitates his students' discovery of the relevance of Jewish customs, literature, prayers and ideas. He also believes that students feel much more comfortable in the synagogue when they know they are competent in Hebrew, so he designs games and engaging exercises to help them learn.

Prior to teaching at Mishkan Shalom, David served as cantor and music specialist at Congregation Ohev Shalom (Wallingford, PA) and Or Shalom (Berwyn, PA). At Mishkan he has led clubs that created and performed plays and raps for Hannukah, Purim, and Passover, as well as storytelling and trope clubs. He enjoys singing all kinds of music: opera, musical theater and lieder as well as liturgical music. David is drawn to teaching in the synagogue because within it he experiences the whole gamut of Jewish life: prayer, education, b’nai-mitzvah preparation, lifecycle, and community.
