Attended Ross University School of Medicine in Dominica, an island nation in the Caribbean, and earned a Bachelor’s of Arts in Psychology from the University of California, Los Angeles. His family moved to Hilo from Japan last summer.

Dr. Yamaguchi says, “I have decided to pursue Family Medicine because it allows me to provide integrated care and to have a long term, close and trusting relationship with patients and their families…I envision myself working in rural areas providing healthcare to underserved communities in Hawaii and the Pacific Islands.”
