Welcome To The World of Vibrational Medicine

Through years of personal study, and decades of research by myself and other pioneers in the vibrational medicine field, we have been able to witness the powerful healing effects of therapeutic sound and its many applications.

The AMI—Acoustic Meridian Intelligence devices I have innovated provide Cymatherapy™, a utilization of healing frequencies, (sound waves), to create vibrant health through our combination of ancient healing methods with advanced sound technology. During my last two decades of exploration and clinical observations, I have been able to witness the immense benefits of this form of therapy, which I brought to the United States in 2001.

The techniques of applying sound trans-dermally to the body resulted in my innovation of the AMI concept and devices. In 2013, the AMI 750 device was nominated for the Thomas Edison Award for Innovation in the Fields of Science and Medicine.

I am dedicated to making this form of therapy available to everyone. My sincere wish is that the information you find here will inspire you to explore the limitless possibilities for vibrant health for your patients, clients and loved ones.
