Our Staff

Jason Schnissel, Executive Director

Jason considers himself very fortunate to have attended a Jewish Day School from grade school through high school.  This, coupled with being raised by a strong Jewish family, instilled a passion for our heritage, culture and traditions. Jason first moved to Aspen as a recent college graduate with the intent to stay for a year and work for the Aspen Center for Environmental Studies. After spending a few months away, he decided to return to the valley. Upon his return he began teaching in our Hebrew School and later oversaw our youth group. Jason was excited to be able to share his Jewish passion and knowledge with our youth. During this time Jason also maintained management positions in the ski industry. In August 2015, Jason began his current role with our congregation. When not working, you'll find Jason making turns - on skis during snow season and bikes the rest of the year. Jason can be reached at or 970.925.8245 x5.


Sima Oster, Education & Family Engagement Director 

Sima Oster grew up on Long Island and attended Jewish Day School from Preschool through High School. After graduating college, she lived on the Upper West Side in NYC where she enjoyed exploring Central Park in running shoes and on bike. When she met her husband, Ethan, Sima moved to northern New Jersey, and together they spent weekends biking, hiking and camping. They look forward to exploring all the activities that our mountains and valley have to offer as they build a family with us here in the Roaring Fork Valley.

Sima holds a master’s degree in the Art of Teaching (MAT) and a certification in Jewish Leadership through Teaching from Brandeis University. She gained experience teaching preschool children in Tribeca’s Jewish Community Project (JCP), while also teaching Hebrew School and building the Bnai Mitzvah program for that community. When Sima became the Hebrew School Director and Preschool Associate Director at JCP, she focused her administrative work on curriculum and program development that instilled a sense of connection in families, children, and teens, always striving for relevance and developmentally appropriate activities for each age range. Sima can be reached at or 970.925.8245 x4.
