In 1971, he encouraged Manuel  “Manolo” Herrán, who had married Guerra's niece, to move to Miami from Atlanta, Georgia, and assist with Sedano's operations.

Herrán, a native of Spain, had moved to Sancti Spíritus, Cuba, as a teenager with his parents and siblings to escape Franco's regime.

Market Sedano's has onsite bakeries and kitchens that produce Hispanic baked goods such as Cuban bread, empanadas, croquetas, and pastelitos.

[citation needed] Besides packaged Hispanic foods and culturally common fresh fruits and vegetables, shoppers can also find typical American fare and products.

In 2018, Sedano's Supermarkets announced a partnership with Takeoff Technologies, a grocery software startup, to debut the first-ever automated, hyperlocal fulfillment center in Miami.

[citation needed] Over the next three decades, Sedano's Pharmacy became a Hispanic drug retailer company with 11 locations from Homestead to Kissimmee, Florida.

Today renamed Republica Havas, the agency has worked with the Herrán family to evolve and grow the storied Sedano's brand across Florida.

In 2020, República Havas led[5] the development of the partnership between Sedano's, Versailles and La Carreta[6] restaurants to help save hundreds of employees’ jobs due to the lockdowns across Florida because of the COVID-19 pandemic.

The management works in conjunction with local and national organizations to provide relief in monetary donations, non-perishable goods, clothing, first-aid kits, and other needed supplies.

As an “essential” business since the onset of the COVID-19 pandemic, Sedano's adjusted operations and policies as required by the Centers for Disease Control and Prevention (CDC), and local protocols.

Additional safety precautions were adopted, including providing hand sanitizer, plexiglass barriers at check-out stations, and limiting capacity as necessary.
