Alex stumbled upon the power of neurogenic tremor response while living as a monk at a Zen monastery in the mountains outside of Honolulu, Hawai’i. Struggling with hip pain, he was able to go through 10-series of Structural Integration by a local practitioner who traveled up to the monastery. During one of these sessions, his body began to spontaneously tremor and shake in a very surprising way – but when he stood up after the session he felt lighter and freer than he had in years.
A decade later, Alex had begun to work professionally as a Structural Integration bodyworker himself, and frequently saw this tremoring phenomenon arise in his clients. When he discovered the work of David Berceli and TRE in 2014 all the pieces came together, and he finally had an explanation for this strange tremoring discharge phenomenon.
This launched a decade of intensive study of the connections between the body, breath, nervous system, and the neurogenic tremor reflex. Alex has integrated a study of numerous bodywork and nervous system techniques including TRE, Structural Integration, Myofascial Release, Zero Balancing, Feldenkrais Method, Visceral Manipulation, Somatic Experiencing, Internal Family Systems, Brainspotting, Safe & Sound Protocol, and DARe Attachment work.
In addition to running a successful group private practice, Alex is an innovative somatic educator – teaching extensively around the world as a TRE Certification Trainer. Alex has taught physicians in China, bodyworkers in Japan, psychotherapists in Kenya, frontline medical workers at major hospital systems in the United States, and, most recently, firefighters at FDNY in New York.
Alex lives in Boulder, Colorado at the edge of Rocky Mountain National Park with his wife, Vanessa, and young daughter where they love to explore the great outdoors.
