About Dr. Holly Castle – Certified Biotherapeutic Practitioner with 20 Years Experience

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

This material combines 5 basic drainage courses I have taken from 4 different practitioners: Drs. Guéniot, Thom, Abell, and Tondelier, as well as my own experience. Many treatment protocols and clinical pearls are included. You will be able to immediately integrate the information you learn from me into your practice.

This interactive weekend course will be part tutorial and part mentoring. I am offering this via Zoom to no more than 15 people. The small class size allows me to answer everyone’s questions. In addition, I ask participants to bring a case on Sunday so we can discuss treatment strategies. I want to convey a way of thinking through a case when using Unda Numbers.

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 you state or province.

What Your Colleagues Have Said

“Dr. Castle’s class was the class I didn’t know I needed. I’ve been familiar with UNDAs and their powerful results for years. I even tried studying them on my own while incorporating into my personal and patient’s care. But after taking Dr. Holly’s class I realized the potential UNDAs really have and it blew me away. What made the class special though is Dr. Holly’s teaching style. She engages us throughout the long weekend with stories and highlights about UNDAs, patient care, her personal experiences, and practice management. It felt part mentorship and part educational.”  Dr. IG
