For decades, former players of Club León and Unión de Curtidores knew exactly where to go when they needed dental care. Gustavo Rodríguez Alfaro's clinic became a meeting point for several generations of Leon footballers. Some arrived recommended by old teammates. Others because they were going through economic difficulties and knew they would find help. For many local football veterans, Gustavo was not just a dentist: he was one of their own. His story is uncommon. He was a professional footballer, shared a locker room with Club León figures, played for Unión de Curtidores, and after leaving the pitch, dedicated almost six decades to attending patients without ever breaking the bond with football. His father, Gustavo Rodríguez Martínez, a native of Puebla, arrived in the city in 1937 after graduating as a dentist from the National Autonomous University of Mexico. He was one of the first specialists established in León and opened his clinic in the Las Fábricas de Francia building, opposite the Plaza Principal. He married Honoria Alfaro, also a dentist. In an era when few women pursued professional studies, she was part of a pioneering generation. The couple had two children: Georgina and Gustavo. Rodríguez Martínez's clinic quickly gained clientele. His grandson Gustavo Rodríguez Junquera recalls that he kept the doors open for anyone who requested attention. Over time, it became a reference for numerous Leon families. In June 1970, when León was one of the sub-sites of the World Cup, the clinic received an unexpected visit. The German Federal Team was staying in Comanjilla and using León's facilities for training. They received a call to attend to one of the German footballers urgently. It was nighttime. The patient was Gerd Müller, considered one of the most important strikers in international football at the time. The player visited Gustavo Rodríguez Martínez's clinic. A photographer documented the consultation, and the sports newspaper ESTO published an interview with the dentist. After the treatment, Müller asked how much he owed. The response was that he had no debt. As a thank you, he offered tickets to one of the World Cup matches. The dentist explained that he already had tickets for the games. Then he asked for autographed photographs. A few days later, he received something more. The German team gave him a ball signed by all its members. The ball remains in the family's possession. Over time, the signatures have faded, but the memory remains intact. Three years later, in 1973, Gustavo Rodríguez Martínez passed away at the age of 65. He had seen his son graduate and begin his own career. Born in León in 1942, Gustavo Rodríguez Alfaro spent his childhood surrounded by two worlds that would shape his life. On the one hand, dentistry. His father, Gustavo Rodríguez Martínez, and his mother, Honoria Alfaro, were dentists and part of a pioneering family in the profession in León. On the other hand, football
