You will need to pre-register to attend our web-based events. The registration link is included with each event's description.


Are you interested in researching Jewish family history and looking for a local network of experts and enthusiasts? 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 and contact us with any questions you have.
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 on the right side of this page. Guests are always welcome. We meet once a month in Denver or Boulder on Sunday mornings generally, at 10 am, from September through June.
JGSCO is a nonprofit organization run entirely by volunteers. Suggested 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 mentoring services for members only. Mentoring may consist of helping you learn to organize your material, recommending web sites, suggesting strategies for overcoming "brick walls", answering specific questions, helping you interpret information and generally teaching you how to conduct your own research.  The mentoring program is NOT a research service, and mentors do not do actual research for you. There is no charge for this service.  A list of mentors and their areas of specialty are available on this web site when you login with your membership ID for a request. Request one of our expert GENMENTORS at a monthly meeting or by email to
Some of our mentors and 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.
And, please remember that all mentors are volunteers.
