Form 990 filings give names without a person identifier; SEC insider filings carry a CIK. It may be a different person.The board
33 listediTime on the board is observed from the annual filings: the IRS files no appointment date, so the bar counts years from the first filing the person appears on - 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 in the tables. The network map shows same-name matches as likely links only, never as confirmed.Time served and departures are observed across annual filings. Observed time served is a lower bound - a member may have joined before the first year on record. The organisation reported 30 voting members of its governing body on its latest Form 990 Part VI; we list 33 in Part VII (Part VII does not always name every voting member).| Name | Role as filed | Since | On the board |
