Caleb Masuda LAc, Dipl. O.M.

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. Before attending FBU Caleb earned a 1st degree black belt in Taekwondo and later trained in Kenpo and MMA style martial arts. It was during this time Caleb studied Tai Chi and Qi Gong; the internal martial arts that relates 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 provide relief for a variety of disorders ranging from 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 to acupuncture’s field of research as a medical technique and healing art. 

Caleb is dedicated to the 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. Similar to 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 is what guides his strategy for the treatment. The use of acupuncture is a way to stimulate the body’s qi along these pathways to respond in an appropriate matter to the 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.

Arezu Masuda, Manager & Founder

Arezu Masuda oversees operations and management of Masuda Acupuncture. Before operating the clinic, she spent ten years in business administration working for a non-medical in-home care company where she managed operations, online and direct marketing, invoicing, payroll, team building, and learned how to care for seniors while incorporating companionship into their care.

While building her professional career, Arezu attended college and university, studying English, Environmental Studies and Business which shaped the eco-conscious values she incorporates both in the office and at home. In addition to managing the clinic, Arezu loves all mediums of art and crafts, blending essential oils, literature, learning medicinal recipes including fermented foods, jun & kombucha.

From a young age,  Arezu was drawn to plants, nature, and ki that we all share which led her to Reiki. While Caleb was finishing up TCM curricula at Five Branches University, Arezu became a second-degree reiki practitioner under Joyce Leonard at Santa Cruz Reiki Works. Arezu loves tea (surprise, surprise.)  Prior to the CoVid-19 outbreak, she always had a fresh pot of herbal tea (tisane) on the warmer and complimentary for each patient. She hopes to once again incorporate this treat by winter.
