Each parish is separately incorporated under the New York State law. There are strict rules regarding the composition and responsibilities of the Board of Trustees. The Board of Trustees oversees the Pastor’s management of the parish. All major decisions about the funds and property of the parish must have approval of the Board of Trustees. Under the New York law, the Board of Trustees consists of:

- The Archbishop of New York, as President of the civil corporation.
- The Vicar General of the Archdiocese as the Vice President.
- The Pastor of the parish as the Secretary-Treasurer.
- Two lay trustees chosen by the Pastor, with the approval of the Archbishop. The trustees of the “Parish of St. Catherine Labouré and St. Colman” are Kelly Seelbach and Jacqueline A. Dachenhausen.
