Hannah began acting professionally at eight, launching a career that included leading stage roles such as Helen Keller at the Tony Award–winning Alliance Theatre, along with performances in The Secret Garden, To Kill a Mockingbird, and The Diary of Anne Frank. Her screen work includes television appearances and dramatic films, most notably a principal role in You’re Killing Me. During five formative years in Los Angeles, she deepened her craft through intensive Meisner training while performing jazz regularly, often singing multiple gigs a day. Influenced by artists such as Sarah Vaughan, Peggy Lee, and Norah Jones, Hannah’s musical range spans jazz standards, pop, R&B, soul, and beyond. Now based in New York City, she performs at venues including Birdland, The Wallace Lounge, and The Triad Theater.
