Deirdre O'Dwyer (she/her) Education Director & Teacher for Kitot Keff & Gan (Grades Pre-K & K)

Deirdre Esther O'Dwyer is a UC Santa Cruz alumna and a Montessori-certified educator, with a research background in the neurology of child development. She starts her days early — rising at 4:30 am each day — to bring her passion for secular humanism, Jewish culture, and child-centered learning into every class she teaches.

Originating from the melting pot of San Francisco, Deirdre deeply values her multicultural roots by taking pride in being simultaneously Jewish, Irish and Japanese. She cares for her father at home and shares her life with her husband, two dogs and three cats. Beyond the classroom, she is also an independent artist, weaving creativity and curiosity into every part of her work and life.

I’m so pleased to be teaching at SJC's Mitzvah Secular Sunday School. During the week, I am a middle school special education teacher for Seattle Public Schools.

I grew up in Philadelphia and attended secular Wednesday and Sunday School at The Suburban Jewish School, where I wish I had been a better student at learning Yiddish.

My own children are Mitzvah Secular alumni from more than a decade ago. Being Jewish is a key piece of my identity, and the opportunity to teach here helps me feel connected to a cherished cultural community.

Jeff Treistman (he/him) Teacher for Kitot Bet & Gimel (Grades 4-7) Classes & B Mitzvah Program Mentor

I grew up in a secular Jewish family (both my parents were atheists, as was my paternal grandmother) in the Philadelphia metropolitan area, and moved to Seattle in 1976 when I was 22 years old. Although I had no formal Jewish education as a child, I have always been interested in Judaism, especially its history. I like to say that my temple was the Overbrook Delicatessen, to convey that we were cultural Jews with the ritual of eating smoked fish on Sunday morning, dabbling in Yiddish repartee with the staff, and dropping some shekels in the tzedakah box for Jewish defense.

I've been teaching at Mitzvah Secular for over a decade years, and am a graduate of the Leadership Program at the International Institute for Secular Humanistic Judaism. This ordained me as a Madrikh (Hebrew) / Vegvayzer (Yiddish) / Guide to officiate youth B Mitzvot.

Differentiation Disclosure

As a small congregation in one of America's fastest-growing metropolitan cities, our Sunday School enrollment can fluctuate a lot year to year, depending on the demographics flocking into and out of Seattle in any given year, so in some years, select Kitot may be merged into fewer classes, which is why we charge the same pricepoint for multiple grade levels. This practice is called differentiation, and we make sure to only recruit teachers with differentiation experience when hiring.
