I grew up in Aiea, graduated from Punahou School's class of '95, and received a Bachelor of Science from Oregon State University. Soon afterwards, I moved to California to attend the University of California, Los Angeles.  I earned my Dental degree from UCLA's School of Dentistry in 2008. 


     Prior to returning home to Hawai'i, I provided a wide variety of dental services in residency at the Sepulveda VA Hospital located in North Hills, CA and as an associate dentist in Northern Los Angeles.  When I returned, I worked both in the dental clinic setting and in private practice on the leeward side of Oahu before finally settling on the windward side.


     Now, I live and work in beautiful Kane'ohe.  I am a proud member of the U.S. Air Force’s Hawaii Air National Guard. My days off are filled with family events and kids activities; baseball, soccer, gymnastics, dance, you name it! However, when I can sneak out, I enjoy playing softball with my fellow Guard members, surfing and golf.


     I look forward to providing you with all of your general dentistry needs.

     I was born and raised in Kaneohe. In 2009, I graduated from Castle High School, where I was active in the wrestling and judo programs. After High School, I followed my passion for wrestling by attending Wartburg College in Waverly, Iowa, where I was an NCAA Division III wrestler and earned my BA in Chemistry. Luckily, I was accepted to a dental school much closer to home, and received my dental degree from the University of Washington School of Dentistry.

     After dental school, I continued my dental training by completing an Advanced Education in General Dentistry residency program. This NYU Brooklyn Langone residency, was held at Kokua Kalihi Valley, and provided training in advanced cases that are more often seen by dental specialists. This training gave me experience in procedures such as surgical wisdom tooth extractions, difficult molar root canal therapy, gum surgery, dentures, and crown and bridge work, as well as day-to-day cleanings and fillings. I completed my training in 2018, and I am excited to be able to join Dr. Oka in serving my hometown of Kaneohe.

     When not at the office, I occasionally get to spend my time coaching wrestling or practicing at the Wadokan Judo club. But most of my time is spent taking care of my daughters. I look forward to working together with my patients to build lasting relationships and to tailor treatment to each patient’s own wants and needs.
