Thom F. Cavalli is a Jungian-oriented clinical psychologist, author, and teacher in private practice in Santa Ana, California, with more than four decades of clinical experience. He earned his Bachelor of Arts at Queens College in a dual major of Fine Art and Psychology, completed a Ph.D. in clinical psychology at Alliant International University in 1979, and was licensed as a psychologist in California in 1981. His Jungian formation came largely through long personal study and analysis with Robert A. Johnson, Pan Coukoulis, Jack Laney, and Laura Brau.

His writing belongs squarely to the post-Jungian alchemical tradition. His first book, Alchemical Psychology: Old Recipes for Living in a New World (Tarcher/Penguin, 2002), introduced a working clinical vocabulary for treating psychological transformation as an alchemical process. His second, Embodying Osiris: The Secrets of Alchemical Transformation (Quest, 2010), reads the Egyptian Osiris myth and the alchemical formula solve et coagula as a sustained image of integration, death, and renewal. He has published widely in Psychological Perspectives, The Jung Journal, Quadrant, and the Journal of Jungian Scholarly Studies, and has taught at the C.G. Jung Institutes of Los Angeles, Arizona, and Vancouver, the Philosophical Research Society, Esalen, the International Alchemy Conferences, Chapman University, and Cambridge.

In his consulting room and his online alchemical coaching practice he works with adults and elders on depression, anxiety, addiction, trauma, grief, relationship and spiritual concerns, drawing on dream analysis, active imagination, and the alchemical operations to help people compose meaning from what is breaking down in their lives. He is currently accepting clients and offers TeleTalk sessions across the United States and internationally.
