From Warehouse to Powerhouse: The 55-year-rise of Dunosusa

Abarrotes Dunosusa has grown from a small bakery supplier in downtown Mérida to one of southeastern Mexico’s largest grocery chains, with nearly 560 stores across five states and more than 5,000 employees.

The company began operations on June 25, 1969, just four days after registering with Mexico’s tax authority, in a modest warehouse on Calle 46 in Mérida’s historic center.

Behind the company’s founding were three Yucatecan entrepreneurs: Gustavo Ricalde, Feliciano Molina, and Manuel Castilla. Originally called “Proveedora del Panadero” (Baker’s Provider), the business focused on wholesale distribution of baking ingredients like flour, sugar, and yeast to local bakeries.

“They were the ‘commodities’ of that era,” said Alejandro Bermejo Arcila, the company’s operations manager.

For more than two decades, the business remained focused on bakery supplies. That changed in 1991 when the company diversified into candy sales, adopting the name Dunosusa — an acronym for “Dulces y Novedades del Sureste” (Sweets and Novelties of the Southeast). The company’s logo still reflects those origins, with letters designed to resemble candy.

Dunosusa’s new format

Strong market response led Dunosusa to add grocery items in 1995, creating the store format that defines the chain today. The first stores to open in this new format were located in Los Cocos, Vicente Solís, and near the city’s newspaper kiosks.

Rapid expansion began in 2004 and 2005 under the leadership of Juan José López Morcillo, who implemented an aggressive growth strategy aiming to open 50 stores annually. Before this expansion push, the chain had fewer than 20 stores, mostly in Mérida, with one location in Oxkutzcab and another in Motul.

Today, Dunosusa operates throughout the Yucatán Peninsula and has expanded into Chiapas and Tabasco. The company even exports merchandise to Belize from its Chetumal distribution center.

One key to Dunosusa’s success has been its emphasis on private-label products. The company offers house brands across multiple categories, from cheese (“Duno El Holandés”) and produce (“El Sembrador”) to personal care (“Dunocare”) and cleaning products (“Dunoclean”). Party supplies are sold under “Dunofiesta” and “Pa’la fiesta” brands.

“Private label is what gives added value and establishes the criteria for product value,” Bermejo Arcila explained.

The company has diversified with specialty formats including My Marketplace, which targets upscale customers with gourmet products, and La Macarena, a cash-and-carry operation for wholesale and industrial clients. Dunosusa has also developed multiple sales channels, including traditional retail, online sales, pickup services, and small neighborhood store formats.

Environmental sustainability has become a priority. The company has invested more than $10 million in solar panel installations, with over 25,000 panels across its operations. Management plans to equip all stores with solar panels in the medium term.

Dunosusa operates three distribution centers in Mérida, Chiapas, and Chetumal, which are supported by an internal vehicle maintenance operation. The company has been socially active for over 15 years through customer round-up donation programs supporting local institutions.

Dunosusa competes in Mexico’s retail market dominated by international chains. Walmart de México controls 65 percent of Mexican supermarket sales, followed by Grupo Chedraui with 19.3 percent. Regional chains like Dunosusa face increasing competition as major international companies continue investing billions in Mexico’s growing market.

Dunosusa joined the National Association of Self-Service and Department Stores (ANTAD) in 2005, becoming part of an organization that represents 157 retail chains operating more than 50,000 stores nationwide. ANTAD members account for nearly half of Mexico’s total retail sales and employ over one million people directly.

The company emphasizes what it calls the “five absolutes of retail”: supply, display, cleanliness, signage, and service. “The customer should arrive at these stores and find the table set,” Bermejo Arcila said.

As competition intensifies with new well-positioned players entering Yucatán’s market, Dunosusa continues adapting while maintaining its customer-focused approach rooted in founder Gustavo Ricalde’s original philosophy of excellent customer service. The company that began with three people in a downtown warehouse now serves thousands of families across southeastern Mexico, proving that regional businesses can thrive in Mexico’s evolving retail landscape.
