Welcome to GDVsource!

GDVsource was established in 2009 by Mary Milroy, and is operated by Mary and Natalina Khavkin. As a dedicated healthcare practitioner and researcher, Mary Milroy has been using Kirlian technology for many years. She was asked by the renowned physicist, Dr. Konstantin Korotkov several years ago to represent his visionary work with the GDV (Gas Discharge Visualization) camera as the East Coast representative for KTI, - home of the original GDV camera - in the USA. She is passionate about the necessity of harmonizing the mind, body and spirit as a means of obtaining and maintaining a healthy, happy and productive life.

This sophisticated electrophotonic technology provides the user with the essential tools and analysis techniques needed to assess the body’s current condition and subsequently monitor changes to help an individual accomplish a whole-body balance that otherwise would be more difficult to measure and direct.

Official GDV products provide doctors, researchers, healthcare practitioners, athletic trainers, and medical and wellness product consultants with the gold standard for measuring the Human Biofield, using a system that is recognized and accepted by science and medical communities worldwide.

There are GDV products available to suit a wide variety of applications and budgets. GDVsource is 100% committed to providing official GDV equipment as well as tools and solutions that improve the way you do business with the GDV product line. We want to hear from new prospective users and loyal customers like you.
