Maria and Aldo Vennettilli opened their family business in 1962, on Erie Street East and Goyeau. Their family grew, as did the business. They had three children: Richard, Tony and Danny. The children learned quickly that it took hard work and dedication for their family business to thrive. In 1967, the Vennettilli Family opened their second store, on the corner of Hall and Tecumseh Rd.

In 1975, the family business moved to Tecumseh and Norman Road, which later was followed by a renovation in 1981. In 1996, Guaranteed “A” moved to its current location at 4735 Tecumseh Road East. It is now known as Guaranteed “A” Fine Furniture. The store was remodeled and expanded in 2000, with the latest products and ideas in the home furnishing industry. Today the third generation of the Vennettilli family is involved in the family business as well
