In 1995, Marzo, a social bridge player, recognized the need for a computer program to enable the building and maintaining of a professional database with information about bridge deals. This would make possible the entering, annotating and classifying data about a deal and permit easy retrieval and printing a variety of forms. An associated deal generator was envisioned. He created the first version of The Bridge Dealmaster and showed it to several authorities in the bridge world. The reception was very enthusiastic and led to additions and modifications. Demonstration of the product at the 1995 summer NABC in New Orleans created additional enthusiasm. Since then, the product has grown, largely because of the continuing stream of ideas from users. The initial concept and framework have not changed.

Ed Marzo enjoys talking with his customers, helping them if they have a problem and suggesting how they might use Dealmaster Pro most effectively.
