Following a near-death experience in 1984, Joyce changed careers and embarked on extensive exploration of indigenous spiritual and healing traditions, which she incorporated in her first book, Cell-Level Healing: The Bridge from Soul to Cell. Dr. Hawkes is the founder of Healing Arts Associates and maintains a private practice in Seattle. She keeps a busy schedule of teaching and conference presentations in the Seattle area, across the the US, and abroad.

Joyce's fascinating science, stories, and rapport with audiences has made her a popular radio and television guest. She has been a featured guest of Art Bell on Coast to Coast Radio and George Noory. Joyce was featured on a national TV special with Diane Sawyer (seen on Turning Point and on Good Morning America), She was also filmed in Japan in 2005 for a documentary. Her brain wave patterns were tested with EEG recordings during meditation (see image upper right) and while doing healing work (lower right) The results were quite unusual, according to Dr. Akio Mori, of Nihon University, Tokyo, Japan. "I've never seen anyone with as highly focused brain patterns as Dr. Hawkes."
