President Porfirio Díaz even invited her to the presidential palace while his wife presented her with gifts including a jewelry box with over 30 jewels. After touring the Mexican provinces, she returned to the capital in 1889, appearing this time at the Teatro El Nacional. On 1 January 1891, Martínez Casado married Isaac Puga, an actor she had met in Spain and who had travelled to meet her in Cuba. Together they had four children. The same year she returned to Spain, broke off her contract with Burón and created her own theatrical company bearing her name. Over the next 20 years, she performed with her company in Cuba, Mexico, Puerto Rico, Colombia, Santo Domingo, Panama, Costa Rica and Venezuela, earning more than three million peso, a veritable fortune. In 1910, now aged 50, Martínez Casado established the "Sociedad para el Fomento del Teatro", a foundation aimed at encouraging Cuban authors to write plays and revive past Cuban theatrical works. In 1911, following the death of her husband, Martínez Casado retired from the stage, giving her last performance in Cárdenas where she played in "Locura de amor" by Manuel Tamayo y Baus. On 28 September 1925, Luisa Martínez Casado died in her home town of Cienfuegas.
