She first worked as a TV host and a correspondent for GMA-7's news and public affairs programs.
But when she got married in 2004, she and her husband moved to Hongkong, where the Italian businessman owns restaurants, disrupting her career.
After her divorce, Miriam moved back to the Philippines and started to be visible in show business again.
Since then, she has been getting recognition for her various stints in the industry.
She was recently nominated as Best Supporting Actress at no less than the Gawad Urian Awards 2010, for the comedy movie Kimmy Dora, where she plays Gertude, the beautiful and much-abused assistant of Kimmy (Eugene Domingo).
Two years earlier, in 2008, she was awarded Best Female Host by the Aliw Awards.
By November of this year, Miriam will be part of TV-5's upcoming show, Broken Hearts Club.
"Sa showbiz naman, [ang balak ko] is to inspire, to inform, equip, entertain, and empower," Miriam told the press.
Miriam, whose career is managed by Annabelle Rama, said that she is happy with the way things are going in her career, but she clearly intends to go further in her career.
According to the 35-year-old beauty queen-actress-entrepreneur: "Pinag-iigihan ko lang talaga. Alam ko na marami pa akong bigas na kakainin bago ko maabot 'yung naabot ng ilang sa mga kasamahan natin sa showbiz, pero happy na ako sa mga na-achieve ko sa ngayon, and I'm taking it one project at a time."
