RRDT Enterprise is primarily engaged in a trading business based in Grace Park, Caloocan that deals with the distribution of food and baking ingredients and supplies in wholesale and retail.

The current enterprise was initially started by the owner's grandmother, Teofila Tiu-Dy, under the trade name Grandeur in the early 1950's and was handed down to her grandson after her retirement in 2007.

The secret of the business' sustainability after all these years is perhaps its continuous efforts to always provide quality-tested baking ingredients and supplies to its customers at the most affordable cost.

After more than 50 years in the business, the current enterprise promises to carry on the legacy set by his grandmother of providing quality products and services to commercial, professional and home bakers.
