Committee Seeks Suggestions for Potential CASA Board Members
The CASA nominating committee, chaired by past president Bill Long, will convene in early spring to consider CASA Board of Directors candidates for the August 2021 ballot. The committee will be recommending candidates for four of the twelve elected seats. The Board of Directors is the governing body responsible for policy decisions and oversight of CASA’s Executive Director. Board members are expected to:
  • Attend all CASA conferences and the Washington D.C. policy forum
  • Participate in monthly board conference/zoom calls and future in-person meetings
  • Attend an annual strategic planning session for the association
  • Assist in member recruitment and retention
  • Represent CASA at events and meetings as requested by the President
CASA attempts to include geographic diversity as well as a balance of agency managers and elected officials on our Board. This year we anticipate the need for a Northern California elected official. Ideal candidates will be familiar with CASA as an organization and preferably will have served on or actively participated in CASA workgroups, committees and events.
If you know someone who would be a valuable board member, please send a brief email to with their name, agency and a few sentences about his or her qualifications. Please send your recommendation by March 15, 2021.
