Richelle, the eldest child of Richard Angalot and Melinda Pacaldo of Bool District, was 15 years old when she first joined a beauty pageant representing Tagbilaran City Schools Division to the Miss Central Visayas Regional Athletic Association (CVRAA) 2004 in Danao City, Cebu. She won third runner-up, Miss Talent and the Best in Fun Wear trophy.
She was one of the sagalas of the Santacruzan 2004 and chosen as muse of Bohol Lions during our Lions District Convention in 2004.
A few months after, she was declared female grand champion in Island City Mall's Campus Discovery Model Quest 2004.
As of September 1, 2007, Rich Asuncion is a Regal Films contract star.Among other Starstruck Batch 4 contestants, Rich Asuncion easily towers over the rest of the female gang. And it’s not only because of her height—there’s a certain glow in her eyes that, if kindled to a passionate fire, could serve her in good stead when, say, Katrina Halili decides to retire. A diamond in the rough an FHM shoot can cut to a shiny gem.
Asuncion is declared First Runner-up during the grand coronation night on March 7, 2009 at the Arenta Coliseum.
