“Katolen’s intensives teach valuable skills much needed in a herbalists repertoire. The weeklong course is transformative, builds confidence and fosters community. Katolen, on top of her vast depth of knowledge, has a special gift as a teacher. She is able to create a container, amidst the intensity of the learning, that feels easy to retain the information and practice the skills taught. Her feedback is constructive and encouraging. I highly recommend this engaging, valuable intensive for all herbalists from any background of training. ”
