After a decade of personal study and practice, Don began ten years of teaching courses in the Southern California area. He became a certified Tarot Grandmaster, has been a member of many spiritual and magickal groups, and is initiated into several Tantric traditions. He holds numerous advanced certificates in clinical hypnotherapy, including teaching credentials, and is a master practitioner of Neuro-Linguistic Programming (NLP). While living in Minnesota he was the Editor-in-Chief of Llewellyn’s New Times magazine and FATE magazine, as well as producing and starring on “The FATE Magazine Radio Hour.” Don has lectured all over the U.S. at virtually all of the major festivals and conventions (and many smaller ones) as well as at universities. He has also lectured in Europe. He specializes on topics including Kabalah, Tarot, Magick, Tantra, Hypnosis, Past Lives, The Chakras, The Sri Yantra, Evocation of Spirits, and Sex Magick.
His books include Modern Sex Magick and Tarot & Magic. His Modern Magick, the most popular step-by-step set of instructions in real magick ever published, has sold over 150,000 copies worldwide. A vastly expanded and revised third edition of Modern Magick is now available. (A very few copies of the second edition of Modern Magick, now a collectors item, are available.) His fantastic mystery, an exciting, magick-oriented first novel called The Resurrection Murders, is currently thrilling readers. He has also contributed to several books including Ecstasy Through Tantra, Planetary Magick, The Rabbi's Tarot, several volumes of The Golden Dawn Journal series, and The Encyclopedia of Magic and Alchemy. Besides his books and contributions to websites, magazines, as well as appearances on TV, radio shows, podcasts, vodcasts and now webinars, Don is the editor of Llewellyn’s free, on-line encyclopedia, has a magick-oriented blog, and is an acquisitions editor for magic(k) and other occult topics.
