I am honored to have the patients that I do—each one special with unique dental needs, and each entrusting my great team and me to always do the right thing to provide superior dental care. With 24 years of practice in comprehensive, interdisciplinary dentistry provided with compassionate care, this local-born Mid-Pacific Institute graduate treats patients by drawing on all dentistry fields using only proven science-based techniques.


Got a cracked tooth or a terrible toothache? Need an implant restored or a wedding-ready smile? I strive for excellence in a health-centric, esthetic-based model of oral care. We offer the latest dental advancements, including CEREC; Invisalign; low-radiation digital radiography; iTero scanner for impressions; and Moonray 3-D printing for accuracy.


Committed to continuing education, I learn from the best. For this University of Washington dental school graduate, these include Spears Dental Learning Center, Kois Dental Institute, Hawaii Dental Forum and my mentor, Dr. Clyde Umaki.


Our convenient downtown Honolulu location is mindful of patients’ busy lives, offering three 10-hour work days weekly.
