At this time there are two interpening courses. The first is the Professional Interpening course which is 100% online and is a prerequisite to the Advanced Interpening course. Advanced Interpening is an in-person training course that will be instructed by the founder of Trichome Institue, Max Montrose. The next available Advanced Interpening course will happen in late 2022 in the Pacific Northwest. Be sure to sign up for our newsletter to receive updates on the course.
