Originally from Tokyo, Dr. Daiki moved to the United States after graduating high school and earned his degree from Palmer College in Iowa. He later established his practice in Chicago, where he trained for 16 years under the guidance of NUCCA pioneers Dr. Marshall Dickholtz Jr. and Dr. Dickholtz Sr., refining his skills through clinical work, research, and development.

Carrying on the legacy of his mentors, Dr. Daiki treats every patient as “family,” guided by a craftsman’s spirit and a commitment to pursuing ever-higher standards of care.
