We’re here to help by providing programs, support, and guidance to find and use resources located in Colorado and throughout the world. Please take a look through our website.

We encourage all levels of research from beginner to advanced to participate and share their knowledge. Take a look at the How to Get Started page where you’ll find useful information for all levels of research, and check out upcoming programs. Guests are always welcome. We meet once a month on Zoom on Sunday mornings. To help folks with their research questions, we start at 9:30 am and the guest speaker starts at 10 am, (Mountain Time) from September through June.

JGSCO is a nonprofit organization run entirely by volunteers. Annual dues of $30 per individual or $40 per household support the administration of the group including speaker and venue fees, website, and operations. Join here.

Need Help Getting Started?

The Jewish Genealogy Society of Colorado offers a Q & A session during monthly meetings.  Come 30 minutes early where we discuss and offer suggestions to your genealogy questions. We have found this is a great way to help enthusiats work through their 'brick walls.' 

Some of our members may also offer private research services. Fees and type of research should be negotiated individually. Results may vary and are not guaranteed, nor does the JGS of Colorado recommend or sponsor any individual researcher.
