Event Sponsorship and Underwriting
Businesses are invited to underwrite various Impact100 events such as the Annual Awards Celebration, Annual Member Meeting, Holiday Reception, Garden Party and Educational Forums. 

Your company can also make a contribution toward event expenses. During the event your company will be acknowledged, and our website and event invitation will feature the name and logo. Contact our Member Events Chair Karen Sherman for more details.

Support your employee in becoming a member of Impact100 Sonoma by making a fully tax-deductible contribution of $1,200 for her one-year membership. $1,000 will go directly to our nonprofit grant-making fund, $200 will help cover operating expenses. Or, your employee can contribute what she is able toward her $1,200 membership and you match her commitment, allowing her a full membership opportunity.

Your business’s generous support of your employee will be acknowledged on our website and in our newsletter.
