"I built this program from the same nervous system it was designed to help."
— Ptim Pellerin, Program Developer
Ptim Pellerin is a late-diagnosed autistic adult with a seizure disorder and a brain lesion affecting left-side hearing and vision. His service dog, Brevé, accompanies him as a medical alert animal. He has spent over a decade developing frequency-based sound as a practical neurological regulation tool — not as a researcher observing from the outside, but as someone who needed it to function.
Calm in Chaos Music Therapy is the systematized, clinically validated expression of that work — combining lived neurodivergent experience with peer-reviewed evidence and purpose-built technology.
