The Pietris Group begins its history in 1930 from Solomos, Corinthia, Greece, with the opening of the first Pietris Bakery Store. The Pietris family succeeded in winning the hearts of all of Corinthia with the two-kilo peel bread, Pietris Tsoureki, and Traditional Pietris Galaktompoureko. And so, after the Panhellenic fame, the idea of creating the first production at an industrial level began, as well as the introduction of the Pietris products in even more stores. In 1992, the first Pietris Bakery Story opened in Corinth. The resonance and love of the people were so great that the production had to be increased, while more retail bakery stores were opened. Thus, Pietris' facilities were founded in Isthmus, with the production of Pastry, Bread, Confectionery, and Sweets, as well as the Pietris Bakery Shop at the most central part of Corinth. At the same time, a shop was founded on the premises of Isthmus, to establish the integrated production of Pietris. Pietris Group became even bigger with the foundation of Pietris Catering with state-of-the-art facilities in Corinth and began to focus on the organization of weddings, baptisms, and celebrations, while founded an enclosed space (Castello Hall, Loutraki) and open spaces (Pietris Estate & Pietris Junior Estate on site of Pietris at Isthmus). In this way, Pietris Bakery stores are spread throughout Corinthia and Arcadia, with the St. Theodoros Bakery Store being a landmark bakery store for the Mediterranean area. Of course, the Pietris Group does not only remain there and is also active outside the Greek borders, with the opening of its first Pietris Bakery Store in Long Beach, California in 2017.
