The Boulder Genealogical Society is here to help you with your family history no matter where you are researching. We also contribute to the greater genealogical community through local history research.

Society meetings are free and open to the public
on the first Tuesday of each month at 7:00 pm
at Frasier
350 Ponca Place, Boulder

We meet in the 4th floor Assembly Room. To reach this room, enter through the Ponca Place lobby and sign in at the table. Take the elevator at the back of the lobby up to the 4th floor. Upon exiting the elevator, turn left (south). The Assembly Room will be on your left.

Note: Frasier is in the midst of a major building project and your usual parking place may not be available. Plan to arrive early to find a spot. Consider carpooling.
