Born in Kundapura, a coastal area in Mangalore, Karnataka, Deekshith aspired to become an actor from childhood. However, he decided to become a professional cricketer later since he loved sports too. After his birth, Deekshith's family migrated to Bangalore, Karnataka, where they brought him up. However, owing to his family's weak financial conditions, Deekshith made up his mind and went back to acting. He kick-started his career with theatre plays and gradually shifted to the small screen. Deekshith also attended a training institute for performing arts named ‘An Actor Prepares’. Famous TV actress Usha Bhandari and actor turned director Ravi Teja are the founders of ‘An Actor Prepares’.
