Member Levels and Payment Options

Member Levels

Impact 100 Sonoma ensures that 100% of each membership ($1000) goes toward funding local grants. The organization is run almost exclusively by volunteer members, but we do have some budgetary needs, so we invite you to become a Member Plus by donating beyond the membership amount. These Member Plus donations help us maintain our website, host member events, recruit new members and many other activities.

  • Basic Membership, $1000
  • Partner Membership, $1100
  • Advocate Membership, $1200
  • Leader Membership, $1500
  • Visionary Membership, $2000
