mandaraMandara Cromwell- Founder, Board of Directors Chair

Mandara Cromwell is the Founder and Board Chair for ISTA (The International Sound Therapy Association), producer of Cymatics~The Science of Sound and Vibrational Healing Annual Conference, CEO and President of Cyma Technologies, Inc., and 2013 Nominee for the Thomas Edison Award for Innovation in the fields of Science and Medicine for the AMI750®.

Experiencing a love for Gregorian chant as a child, Mandara continued on her sound journey after college, traveling to India to study Sanskrit chant, yoga, Ayurveda and meditation. Years later she was introduced to the world of Cymatics with the meeting of Dr. Peter Guy Manners, a British osteopath who discovered audible soundwave frequency patterns that effect cellular regeneration. Manners worked in collaboration with a group of scientists and medical doctors, for decades, formulating biosignatures and healing frequencies for each part and function of the body.  These “Cymatic Signatures” create cellular symphonies that nurture and nourish our body, mind and spirit, resulting in a state of harmonious health. Since Manners passing in 2009, Cyma Technologies continues the research and development of therapeutic sound devices implementing therapeutic audible frequencies.

Mandara Cromwell lectures on behalf of the International Sound Therapy Association—an organization dedicated to increasing the public’s awareness of the power of our thoughts and words, and sound in our environment.  ISTA is also dedicated to promoting therapeutic sound modalities to the healing world.

In addition to her classical background, Wendy has been studying, teaching, and practicing the healing effects of sound, music, and vibration for over 30 years, and has worked with many of the leaders in the field.
