In 1946, when Darrow was 13, his family returned to Puerto Rico, where he discovered his roots and grew to love a country he had not known. He graduated from Academia del Perpetuo Socorro high school in Miramar, Puerto Rico, as class President before enrolling in the University of Puerto Rico. There he studied political science and acting, and worked as a part-time English-language interpreter. During his third year at the University, he was awarded a Scholarship (the first of its kind) to attend acting school. Thereupon Darrow moved to Los Angeles, where he enrolled in the Pasadena Playhouse. He met and married his first wife, Lucy and they went on to have two children, Denise and Tom. Darrow graduated with a Bachelor of Arts in theater arts.
