About me
I was born in South Korea and moved to Southern California when I was two. My parents worked tirelessly to support our family, and the strength of our community played a vital role in our success. I felt a deep desire to give back meaningfully — and for me, there was no better way than by becoming a doctor.
My mother inspired me to pursue what I value most: caring for others like family. I earned my bachelor’s degree from the University of California, Riverside, and my Doctor of Osteopathy from the College of Osteopathic Medicine of the Pacific. I completed my family medicine internship and residency at the University of California, Irvine. I’m board-certified by the American Board of Family Medicine and proud to be a member of the American Osteopathic Association.
About my practice
Being a husband and father has taught me the importance of family and the value of treating others with respect, attention, and compassion. While providing the best and most up-to-date, evidence-based medical care is essential, strong relationships and teamwork are just as vital to achieving health, happiness, and success. As a doctor, I aim to empower my patients to make informed decisions that positively impact their lives.
As a family medicine doctor, my areas of interest include disease prevention and wellness, geriatric medicine, and minor procedures such as biopsies, cyst removal, and laceration repair.
How I thrive
Work-life balance is key. I try to get a good night’s sleep, exercise regularly, follow a well-balanced diet, and nurture positive family relationships. I also enjoy golfing, hiking, swimming, and biking.

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:
- accessible exam rooms and medical equipment;
- 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
- 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, civil-rights-coordinator@kp.org, 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.
