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

Homeopathy is my passion. I specifically attended NCNM in order to practice classical homeopathy. I graduated from NCNM in 1997. I have studied and used Unda Numbers since 2001. I was awarded advanced certification as a Biotherapeutic Drainage Practitioner in 2019.

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 it via Zoom to no more than 15 people per class. 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 credit is not available because it is a product specific course. The course will not be recorded out of respect to Seroyal and their educational materials. So you’ll be taking the course for your personal enrichment. All that said, I believe it will be worth the price of admission.
