Board of Trustees
The DFI Educational Trust’s Board of Trustees is comprised of volunteer trustees with chair, vice chair, secretary and treasurer officer positions.

In addition, the president and treasurer of DFI serve as members of the Trust board during their terms at DFI. Emeritus and honorary trustees may be appointed as non-voting members of the board.
As part of their commitment to the Trust and its mission, all board members actively participate in fundraising by organizing events, spearheading annual drives, and leading other such efforts. In addition, all board members make personal financial contributions to the Trust.
