Yes, she's Jeanette Delgado's sister! And how many ballet companies can claim to have two sisters, both of them principals? And both of them beautiful? :-D
Patricia Delgado is the older of the two sisters (Jeanette came first here because I presented them alphabetically), and she had the same training Jeanette had, at the same schools. She's been a principal dancer with the Miami City Ballet since 2007.
Patricia's dances have included the 'Man I Love' pas de deux in Who Cares? and Sanguinic in The Four Temperaments.
Patricia has never had any rivalry issues with her kid sister, a testament to how their mother, a psychologist, and her father, a teacher, raised them.
