MDBA History

In 1979, a handful of East Bay beekeepers got together for the purpose of buying beekeeping supplies and bee packages in bulk. So began the Mount Diablo Beekeepers Association (MDBA), now one of the largest beekeeping clubs in California. The group started calling itself a club in 1982 and held meetings twice a year. With around 20 members, the club organized a barbeque, grilling T-bone steaks on a Weber grill, and sharing the camaraderie built around a common interest. Everyone had a good time so they made the barbeque an annual tradition. To attract more members, Steve Gentry placed an ad in the Classifieds—under the pet section—in a Berkeley newspaper. Beekeeping was still an unusual hobby.

In the 1990s, the club met in a small meeting room at Larkey Park. Club members began a lending library, a newsletter, and a swarm list. One member, Stan Umlauft, designed a logo with the MDBA letters inside a hexagon, incorporating the symbols of a mountain and honeycomb. During this time, the MDBA stepped up its work in public service with members volunteering at county fairs, schools, and community events to try to educate people about honey bees and beekeeping. The varroa mite had arrived and changes in agricultural practices were contributing to a worldwide decline in the honey bee population.

Today MDBA is an established institution with an active membership of 300 to 500 members of mostly hobbyist and small commercial beekeepers from the Bay Area. The club includes members of all ages, including students, whose participation helps ensure the continuation of this historic craft. From its initial start as a buyers club, the MDBA’s purpose today is to promote beekeeping though education, workshops, and mentoring, and to enhance the public’s understanding of honey bees, including their importance as pollinators. A primary objective of MDBA continues to be to encourage fellowship and goodwill among all people engaged in apiculture.
