About me

Born on Oahu and raised in Mililani, I am a graduate of the Kamehameha Schools, the University of Hawaii at Manoa, and the John A. Burns School of Medicine (JABSOM).My tutu (grandfather) inspired me to honor the Hawaiian culture and to pass my heritage on to the next generation. He stressed the importance of ohana (family) and encouraged me to learn the Hawaiian language. In his last years he was the caretaker of the Queen Liliuokalani Children’s Center in Nanakuli. Now, a decade after he passed, I am blessed to be a practicing physician in Nanakuli at the Nanaikeola Clinic. My family and I make the Hawaiian language and culture a part of our daily lives.Staying in Hawaii for my medical education was one of the best decisions I’ve made. The communities, patients, and families I work with have helped to make me the kauka (medical doctor) I am today.

About my practice

Through the Department of Native Hawaiian Health as well as community organizations such as Protect Kahoolawe Ohana, I learned about health disparities that Native Hawaiians and other Pacific peoples experience. There is a large population of the medically underserved in our own backyards. Although these people exhibit some of the highest rates of hypertension, diabetes, heart diease, and obesity, there are few physicians native to these groups. As an internal medicine doctor of Hawaiian ancestry I am able to help meet this need.I am board certified by the American Board of Internal Medicine and am currently an assistant clinical professor in medicine at JABSOM. My professional activities include membership in the Ahahui o na Kauka, the American College of Physicians, and the American Medical Association.Following my training in the University of Hawaii Internal Medicine Residency Program I served as chief medical resident. This experience provided tools that assist me in being a lifelong learner and in continuing to pursue my interest in medical education.Joining the Hawaii Permanente Medical Group has allowed me to practice alongside great colleagues and staff. Working at Nanaikeola, I am privileged to practice medicine on the beautiful Waianae Coast amidst the largest population of Native Hawaiians in the world.Taking care of someone’s health is more than treating physical ailments or making numbers look good. Health encompasses spiritual well-being, ohana, and culture. One thing I enjoy most about medicine is the relationships I build with my patients and their families, and I look forward to the moolelo (stories) they tell me every day.

How I thrive

To stay physically and mentally healthy, I spend time with my extended family and friends and try to stay in touch with the aina (the land) and kai (the ocean). My faith is a big part of my spiritual health. I also try to ai pono (eat healthier) and to exercise. To re-charge my battery, I like to go holoholo (out and about for fun), hunting, and fishing.

Kaiser Permanente works together with participating providers to ensure all cultural competence obligations are met. We are dedicated to ensuring that services are provided in a culturally competent manner to all members, including those with limited English proficiency and reading skills; as well as those with diverse cultural and ethnic backgrounds.

Accommodations for Individuals with Disabilities

Kaiser Permanente is committed to providing accessible facilities, services, and programs for all members, visitors and individuals with disabilities. In compliance with federal and state laws that prohibit discrimination based on disability, Kaiser Permanente provides:

  1. accessible exam rooms and medical equipment;
  2. free auxiliary aids and services to ensure effective communication with individuals with hearing, vision, cognitive, and/or communication-related disabilities, including qualified sign language interpreter services and informational materials in alternative formats (large print, audio tape/CDs, accessible PDFs or Microsoft Word documents, electronic texts/disks/CD-ROMS, and Braille); and
  3. access to service animals, except where the animal poses a significant health or safety risk(s) to others.

For more information about access to a specific facility or provider, or if you believe that Kaiser Permanente has failed to provide appropriate access or services or otherwise discriminated on the basis of a disability, please contact Member Services toll-free 1-800-966-5955 or TTY 711, Monday through Friday, 8 a.m. – 5 p.m. or Saturday, 8 a.m. – noon. You may also contact or file a grievance with the Kaiser Permanente Civil Rights Coordinator in person, by mail, fax or email at: 711 Kapiolani Blvd, Honolulu, Hawaii 96813,, or toll-free 1-800-966-5955, TTY 711.

The availability and use of the Kaiser Permanente grievance procedure does not prevent a person from filing a complaint of discrimination on the basis of disability with the U.S. Department of Health and Human Services, Office for Civil Rights or the Hawaii Civil Rights Commission.

Kaiser Permanente uses the same quality, member experience, or cost-related measures to select practitioners and facilities in Marketplace Silver-tier plans as it does for all other Kaiser Foundation Health Plan (KFHP) products and lines of business and uses the same geographic distribution consideration to select hospitals in Marketplace plans as it does for all other Kaiser Foundation Health Plan (KFHP) products and lines of business. The measures may include, but are not limited to, HEDIS/CAHPS performance, member/patient complaints, patient safety scores, hospital quality measures, and geographic need. Members enrolled in KFHP Marketplace plans have access to all professional, institutional and ancillary health care providers who participate in KFHP plans' contracted provider network, in accordance with the terms of the members' KFHP plan of coverage. All Kaiser Permanente Medical Group physicians and network physicians are subject to the same quality review processes and certifications.

A narrow network is defined as a tailored, tiered or high-performance network that has 80 percent or less overlap with a health plan’s broadest network offered to a member in any type of plan offered by that health plan. Kaiser Permanente does not have a narrow network with respect to its Marketplace plans. Members enrolled in Kaiser Foundation Health Plan (KFHP) Marketplace plans have access to the same provider networks as members enrolled in all other KFHP plans.

Information about a practitioner is provided to us by the practitioner or is obtained as part of the credentialing process.
