36 chapters statewide

With 36 chapters statewide, CNPS offers many opportunities to get involved and have fun. Each chapter is unique and has its own priorities based on chapter member interest.  All enjoy the strengths and legal benefits of being one incorporated non-profit organization, but chapters elect their own officers and manage their own chapter budgets.

If you’d like to change/update your chapter affiliation, please contact us at membership@cnps.org or (916) 738-7604.

Representatives from all 36 CNPS chapters meet four times a year during quarterly meeting weekends.

Quarterly meetings and chapter council sessions are open to all CNPS members and friends! Learn more here.
