Board at a glance
Tenure and departures are observed across annual filings. Observed tenure is a lower bound - a member may have joined before the first year on record. The organisation reported 10 voting members of its governing body on its latest Form 990 Part VI, which matches the board listed here.
Renewal outlook
High-priority approach observed from annual filings
- Large organisation (revenue $177m) - the scale that runs a formal, external board search.
- The board chair has served at least 7 years (observed across filings) - a chair transition may be approaching.
- 8 of 11 board members have served at least 5 years (observed).
A computed likelihood from the observed filing history and filed revenue. It is not a confirmed vacancy, and this edition never states that a nonprofit is recruiting. "Departures" mean a board member was on the previous filing but not the latest one, which usually means a seat opened but can also mean they were simply not listed that year.

The board is the directors and trustees named in Part VII of the organisation's annual IRS Form 990; officers and senior staff are listed separately below, not counted as board. The IRS files no appointment date, so tenure here is observed from how many years a person appears on the filings - a lower bound, not a filed start date. Names are exactly as filed. The IRS publishes no person identifier, so this edition does not yet link a person across organisations.
