Shabbat Services

Please join us for Shabbat services every Friday evening at 7 PM.  Shabbat Services are also held on the first Saturday of every month at 10 AM, when we honor someone special in our Congregation. Our services are in person and online through Zoom  At the conclusion of services, enjoy our Oneg Shabbat.

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!

Our annual pledges have not changed in a long, long time.  Pledges are $600 a year. About 10 years ago, we added a second fee of $400 per year. The second fee goes to our Religious Leader account, and pays for our Rabbi, plus cantors and other religious leaders that may serve our community.  The total is $1000 per year, or $83.33 a month. You can pay monthly, quarterly, semi-annually, or annually.  We can also charge your credit card automatically.. If you would like to support our Synagogue and prefer a different amount, please let our office know.

We are a non-profit organization so your pledges and donations are tax-deductible.  Please use our website or contact the Synagogue office to make payments.

You are always welcome at our Synagogue, regardless of your ability to pay.
