Join the Sonoma League and enjoy membership benefits!

League members receive periodic emails (known as “eBlasts") with updates on key preservation issues in Sonoma and the surrounding area, details on upcoming League events, and links to important preservation matters. 

Members enjoy complimentary admission to most League educational events including lectures and ZOOM meetings. Any League function that has a social element with food and drink will assess a modest cover charge.  This category includes any garden parties, award receptions and the annual holiday party. 

Members have free access to research files at our Sonoma League's 'Heritage Center at the Maysonnave House.'  Also, members qualify for discounts in renting the Maysonnave Board Room and the Maysonnave Garden for events. There are no external social events being held inside the Maysonnave House with the exception of the annual holiday party.  Contact our Events Manager Lisa Janson at (415) 259-9458 or at for details.
