After his popular turn on Ugly Betty, Alejandro jumped between some of the most popular series of the late 2000s. He built an admirable résumé, first landing the role of Dan Reyes on the James Woods legal drama Shark, and following that success with a quick two-episode turn as Esai Alvarez on Sons of Anarchy (via IMDb).
In 2009, Alejandro appeared on NBC's hit supernatural drama Heroes, and did a four-episode arc on Mary Louise Parker's Weeds. On Weeds, Alejandro plays the revolutionary leader Rudolpho, who helps Quinn (Haley Hudson) kidnap her mother, Celia Hodes (Elizabeth Perkins). After they realize that no one is willing to ransom the toxic Celia, they dump her back in Texas.
After finding success on Weeds, Alejandro landed quick roles on The Mentalist, Psych, and Parenthood, as well as a substantial 17-episode arc on California cop drama Southland. It was his big recurring role on an HBO hit, however, that really took his career to the next level.
