The namesake of Brgy. Dalandanan came from the impressive line of dalandan trees that used to distinguish the area. The barangay celebrates four fiestas, all in all, depending on which part you lived. Residents near the border of Esteban celebrates the fiesta of San Roque every May, those in San Simon celebrate the feast of San Pedro in June, Belando residents observe the fiesta of the Sto. Nino in January and those who lived near A. Marcelo hold the feast of the Black Nazarene every January. In addition to its multitude of fiestas, Brgy. Dalandanan is also home to Puregold's Valenzuela City branch, Valenzuela City Science High School, the Astro Dome and Victory Fireworks Factory.
