Esta Navidad fue un recordatorio de lo que realmente importa.

En Barranquilla, Colombia, tuvimos el honor de apoyar la labor de la Fundación ANDA, una organización que trabaja todo el año por la dignidad y el bienestar de los adultos mayores y los niños de comunidades vulnerables.

Gracias a su trabajo constante, este año se celebró una fiesta de Navidad para 80 niños, compartiendo alegría, regalos y momentos que dejan huella. ANDA no solo acompaña a los abuelos durante todo el año, sino que también integra a la comunidad, creando espacios de cuidado, respeto y esperanza.

Gracias a todo el equipo de la fundación por su entrega, amor y compromiso con esta comunidad. Es un privilegio poder apoyar iniciativas que transforman vidas desde el corazón.

Con gratitud,
Alexandra
