website-about-caleb-smallCaleb Masuda is a California-licensed acupuncturist ( and a Diplomate of Oriental Medicine ( He earned his Master’s degree in Traditional Chinese medicine from Five Branches University in Santa Cruz. Caleb grew up interested in martial arts, which led him to attain his 1st-degree black belt in Taekwondo and afterward trained in Kenpo and MMA inspired by Muay Thai. During this time, Caleb studied Tai Chi and Qi Gong, the internal martial arts that relate functionally to acupuncture and traditional medicine. In Santa Cruz, he worked as an intern for the Mental Health Client Action Network (, where he treated many in the community who otherwise would not have seen a physician. 


Caleb’s treatments relieve various disorders, including chronic pain, mood disorders, and gastrointestinal complaints. He uses acupuncture and its modalities based on Traditional Chinese Medicine while including effective modern approaches that find their way into acupuncture’s field of research as a medical technique and healing art. 


Caleb is dedicated to understanding how qi can heal or cause dysfunction in the body. Qi is a word that is used to describe energy, and this energy is what flows through our body. Like a dam full of sticks and debris, the flow may cease; in humans, this causes pain and other disorders. Like a stream, our body has ways to move energy along a trajectory but sometimes can become impaired. Caleb’s diagnosis of these pathways and meridians on the body guides his treatment strategy. The use of acupuncture is a way to stimulate the body’s qi along these pathways to respond appropriately to discomfort and imbalance. Caleb’s interest in qi guided him to Traditional Chinese Medicine, and he continues to use the skills he accumulated over the years.
