Steve Liu is a licensed acupuncturist from Tucson, Arizona, USA. He was also an electrical and laser engineer in Silicon Valley, with a degree in electrical engineering from San Jose State University, USA. He has combined photobiomodulation (PBM) therapy with acupuncture to treat acute and chronic pain conditions since 2000.

He is the inventor of the FAST Protocol for treating chronic soft-tissue pain and curing it in less than ten treatments.

Steve has been a member of the North American Association for Photobiomodulation Therapy (naalt.org) since 2001 and served as its president from 2008 to 2010. He was the President Emeritus of the Arizona Society of Oriental Medicine and Acupuncture.

He founded the American Society for Laser Acupuncture Therapy (aslat.org) and has served as its president since 2006.

He has developed treatment protocols that integrate Chinese Medicine, PBM Medicine, Functional Medicine, and Lifestyle Medicine to successfully treat chronic pain, peripheral neuropathy, age-related macular degeneration, autoimmune diseases, and the slow progression of Parkinson’s disease. He calls this unique integrative approach “TCM4.0,” or the fourth generation of Traditional Chinese Medicine (tcm4point0.com).

Steve retired after more than twenty-five years of practice in July 2025. He is now dedicated to passing on his clinical skills through TCM4.0 and the FAST treatment protocols to future generations of healing practitioners through his online school, HanLin Center for Integrative Medicine (hanlincim.com).
