Shabbat Services

Friday - 7:00 PM - In person and online through Zoom.
Shabbat Services are led by lay leaders and Rabbi Moshe Halfon.


On behalf of Mt. Sinai, we are delighted that you are interested in membership in our Congregation.

Through the years Mt. Sinai has been home to individuals and families who come from different backgrounds and live different lifestyles, yet share a deep sense of friendship and community through the extended family of Judaism. We welcome interfaith families in all aspects of our congregational life.  Our diversity and strong community feelings are evident at every gathering and meeting, making Mt. Sinai a very interesting and dynamic environment.

We function as both a synagogue and as the Jewish community center of Cheyenne. We encourage you to participate in the life of Mt. Sinai as you consider membership.

Please join us for Shabbat services Friday evenings at 7 PM and Saturday mornings at 10:30 AM.  At the conclusion of services, please allow us to welcome you at our Oneg Shabbat.

We also have a wide range of cultural activities and events.   Attend our meetings, classes, and activities, volunteer to assist in our events, and learn more about us!

If you have any questions, please contact us at [email protected].
