The ALF appliance was created by Dr. Darick Nordstrom. His curiosity reached well beyond the teeth, into sleep, posture, osteopathy, and the way the tongue, lips and cheeks work together, and out of that curiosity came a light-wire appliance designed to work with the natural function of the mouth rather than against it. He began using it in his practice in the mid-1980s, and it has been part of the conversation about function, breathing and growth ever since.
He taught that the problems we see in the mouth are often tied to the stress and trauma a body has lived through.
He has encouraged his students to become independent thinkers who have a reverence for Nature and respect for science.
His work continues to influence clinicians and families around the world, and every version of ALF taught today traces back to it.
Over the years, ALF has been taught by many clinicians in many places, and each teacher has shaped it through their own experience. The result is something like a language with regional dialects. The vocabulary is shared, but the accent, the emphasis, and sometimes even the meaning of a word can change from one teacher to the next.
We think that is worth saying plainly, because it explains why two providers who both describe their work as ALF may approach the same patient in very different ways. It is also why one of the most helpful questions a family or a colleague can ask is simply, "Where, and from whom, did you learn?"


Through The Synergy Academy, providers have access to more than a decade of Dr. Nordstrom's original teaching, gathered into one convenient, curated online learning library. That library is the fruit of more than fifteen years Dr. Angie Tenholder has dedicated to sharing his work with the provider community.
Dr. Nordstrom always encouraged his students to become independent thinkers who figure things out for themselves, and Dr. Tenholder took that to heart. Over the years, her own clinical experience, and the science that helped her understand it, grew into a way of practicing and teaching that is now her own. Today she offers that version as Synergy ALF, taught through The Synergy Academy and part of NeuralFORM, where the ALF appliance is one option among several.
ALF is part of the roots. NeuralFORM is where those roots have grown wings.
OraLase, a laser sequence created by Dr. Darick Nordstrom, has a roots page of its own.
