“Studying with Karyn and Sarah was hands-down one of the most special, most energizing, and most challenging experiences of my life. I completed the full-time program in 2015 and I constantly draw on the wealth of knowledge I gained during that time. Offerings such as materia medica, medicine-making, and gardening are invaluable and unique to this program. Karyn and Sarah are accessible, generous, and energetic instructors who are deeply committed to their students and to the practice of truly holistic energetic herbalism.”               Gina Badger, Graduate of the full-time program, 2015




“Blue Otter is a dream come true- it’s incredible to have the opportunity to be completely immersed in plant medicine through this full time program. The teachers are exceptional, supporting you to learn an extensive understanding of plant medicine and physiology, and a deep understanding of how to work with clients. The herb garden is an incredible resource where you can actually spend time with the plants you learn about, getting an opportunity to learn how to care for them as well. As a student, this class is a safe container to also do work on yourself, so you can become a strong practitioner. I can’t thank these two wonderful folks enough for the incredible support and encouragement they have provided through this program- Karyn and Sarah truly hold this medicine as sacred, and I recommend their school to anyone who is ready to do this work in a deep way. ”
