CCCHS video at Lesher Foundation "Newsmakers" Speaker Series

On November 2, 2015, the Contra Costa County Historical Society was chosen to be the non-profit "partner" for that night's lecture in the "Newsmakers: Lesher Speaker Series" held at the Lesher Center in Walnut Creek. In addition to a generous donation of event tickets to the society, media sponsor KTVU Channel 2 sent a video crew to the Center to make a video highlighting some of our accomplishments. The 2 1/2 minute video was screened to the audience at the event, and a copy of the finished product was given to the Society to use as it sees fit. You may see the video shown that night by clicking on this link.

Looking for a gift for that hard-to-buy for history buff? The History Center offers a wide variety of books, photographs and services that they will just love. A membership in the Contra Costa County Historical Society makes a great gift too. For details on Society membership, whether for yourself or as a gift, please click here.

CCCHS: The Video!

Thanks to the tireless efforts of Board Member Steve James, producer/volunteer Santiago Chen and many other volunteers at the Center, the Contra Costa County Historical Society has released a YouTube video showing the many facets and facilities available to the public at our History Center in Martinez. If you wish to see the video, click on this link.

The Contra Costa County Historical Society's mission is to preserve for the benefit of the people of our County, the relics of our past. We are using the World Wide Web in order to give more of us access to the wonderful stories of the people who lived in our County, so many years ago. The Society hopes that these Web pages will bring the people of Contra Costa's present, closer to those who lived, worked and died in our County and who are, our History.
