New and Improved Process

In January 2022, a new bylaw was approved by the membership regarding how the Board of Directors roles are filled, moving from a below-average voter participation election, to a process for an approved slate. 

This new process is used by many other membership organizations, and will better support ONS’s ability to ensure the Board of Directors continue to represent the diverse population we serve while also ensuring the balance of competencies exists as selected Board members and the landscape continuously change. The approved slate would also ensure that the most qualified and diverse group of people and perspectives represent our membership.
