Besides her many TV guest appearances, Luise has worked under the direction of British Dirctor Frank Dunlop at the Ahmanson Theatre in Los Angeles and the Brooklyn Academy in New York as Essie in "The Devil's Disciple". Luise also returned to the Ahmanson in a revival of "The Best Man". At the Westwood Theatre in LA, she essayed the role of Rumplestiltskin in Anne Sexton's "Transformations" and that of "The Young Girl" in the LA production of "Ceremonies in Dark Old Men". Miss Heath's portrayal of "The Madame, Lucille" under Alan Miller's direction in the Back Alley Theatre production of "A Walk On The Wild Side" and the perky hot to trot "Young Miss" in The Group Repertory Theatre's production of Le Ronde's "10-Lovers-10" are two examples of the diverse nature of Miss Heath's talents.
