Mandara Cromwell is an entrepreneur, researcher, inventor, and author. As president of Cyma Technologies, she oversees the manufacturing of the Acoustic Meridian Intelligence devices. Her patented invention, the AMI 750, was nominated for the Thomas Edison Award for Innovation in the Fields of Science and Medicine in 2013.

In 2002, she coined the term, “cymatherapy,” to refer to her continuation of the work of British osteopath Dr. Peter Guy Manners, with whom she studied extensively. A long-time proponent of sound as a healing modality, Mandara has spent more than two decades researching the efficacy of sound's visual and auditory aspects, and many applications for improving health.

In 2017, she produced the Cymatics: The Art and Science of Making Sound Visible conference, which featured never seen before sound-made-visible images of the healing frequencies found in her own sound therapy devices. She acted as co-producer on two short films created at the University of Florida utilizing cymatic images — Dance Divine featuring dance, yoga and the sound images, and Full of Stars, a short film showing three dimensional views of the healing frequencies.

As a published author of Soundflower: The Journey To Marry Science and Spirit, she is a sought-after speaker for conferences, seminars, and radio shows. The creator of The Soundflower Experience, a sound/visual meditation for relieving stress, along with many other sound inspired products, she continues to create new ways to apply the principles of resonance to heal the world.
