La Crescent Montessori & Stem School's network

5 people3 organisationsi5 people and 3 organisations on this map.The large node is the subject of this page. Solid lines are what the register itself records (5). Violet dotted lines (3) are likely: the same full name sits on the current board of another organisation in the same register and region. Form 990 filings give names without a person identifier; SEC insider filings carry a CIK. It may be a different person.

The board

5 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.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 5 voting members of its governing body on its latest Form 990 Part VI, which matches the board listed here.
