While I rarely offer workshops in the USA these days, there is an active community of Deep Imagery practitioners there. The International Institute for Visualization Research, a non-profit that grew up around my work, maintains a US based website. Check out deepimagery.net for information on the IIVR and USA and Canadian workshops and trainings. The IIVR also certifies deep imagery practitioners world wide, after they have completed the three year Core Curriculum training in the Personal Totem Pole Process.
