Sustaining Membership Status

Sustaining Members are Corporate Member firms who have responded to a volunteer call for contributions to a special fund to supplement dues income so as to further DFI's educational goals. The contributions are to be used as follows:

  1. To continue with and improve upon DFI's Continuing Education Seminars, so as to allow DFI to remain a leader in information transfer for the deep foundations industry.
  2. To support the Scholarship Fund -- named the Paul DeBruyn Memorial Scholarship Fund -- in honor of our late member who first came forth with the idea of initiating a scholarship fund.

Both The Sustaining membership Fund and the Paul DeBruyn Memorial Scholarship Fund are managed by the DFI Educational Trust.

Sustaining Members meeting a minimum level of contribution are listed on the Homepage of the DFI, on the inside cover of the Annual Conference Proceedings and other publications and on the Sustaining Members Plaque with a legend plate for each year of contribution.
