About Dr. Holly Castle

I am a naturopathic doctor licensed in Oregon, Arizona, and Colorado. My study of homeopathy began in 1987 with classical homeopathy. While attending the National College of Naturopathic Medicine (1993-1997), I continued my homeopathic studies with Paul Herscu, Rajan Sankaran and the Sankaran group, Massimo Mangialavori, Vassilas Ghegas, and others.

In 2001 I began studying biotherapeutic drainage with Drs. Gerard Guéniot, MD, Dickson Thom, DDS, ND, Robert Abell, ND and Pierre Tondelier, MD. I was awarded certification as a Biotherapeutic practitioner in 2019. My education in homeopathic drainage continued with German Biological Medicines and techniques. In addition, I have an extensive background in both vitalism and functional medicine.

Since 2017 I have been mentoring and sharing my knowledge and expertise with professional colleagues and naturopathic students. For those taking my classes, I am committed to providing straightforward, easy to apply information that is immediately useful in clinical practice and improves patient outcomes.

About The Class

In addition to my own experience and personal research, this material combines multiple sources including several books and the lectures from 4 different drainage practitioners: Drs. Guéniot, Thom, Abell, and Tondelier. Many treatment protocols and clinical pearls are included. You will be able to immediately integrate the information you learn from me into your practice.

Each participant will receive a PDF copy of the basic lecture materials. Treatment protocols and clinical pearls will only be part of the live class material.

Continuing education varies from state to state. You will be provided with a letter of attendance that includes details you may need to apply for continuing education in your state or province.
