Don Simmons
President, Board of Directors
Don Reed Simmons is a pioneer in the world of Sound Therapy and has been the President of ISTA since 2009. Simmons’ journey in Sound Therapy began years ago growing up on a farm listening to sound of cows mooing in the early morning. It was that very sound that soothed his nerves when he found himself in a life threatening hospital moment in his his early 20’s. After many years in radio as an announcer and the film industry as a producer/director, Simmons took a deep dive into his passion of helping others.
With ISTA, Simmons has taught Sound Therapy to over a thousand students through the years. He created GB2, (Gongs, Bells & Bowls) an outreach program for ISTA; and the Sacred Sound Ministry, a program teaching the power of Sound as a prayerful, healing modality. He has co-hosted numerous Sound Conferences since the inception of ISTA and has performed at countless venues, performing and teaching the Power of Sound, from churches, to Hospice Care Centers, to Parkinson’s hospital care centers, to cancer support groups, to children’s autism centers and many, many more.
Having trained with Jon Kabat-Zinn, Thich Nhat Hanh, and a Hawaiian Shaman Spirit Guide, Simmons has been a life long meditation practitioner, teaching meditation, mindfulness and compassion with the use of Sound as a modality of relaxation, balance and wellness since 1994. He has been a speaker many times on the subject of Meditation and the power of Sound.
