About Dr. Yoon

Philosophy of care

I believe my role in your care is providing a safe space to discuss your medical issues without judgment or bias. I create partnerships with my patients on plans to help tackle these issues.

Why I entered medicine

I was always fascinated and intrigued by the human body and all the ailments that come along with it. That is why I chose general internal medicine. I never know who will walk in the door with what problems. Even common problems show up in different forms in different people.

Community involvement

I trained in a program where we provided medical care for underserved and uninsured people. I look forward to learning the most immediate medical needs in the community and volunteering my time to provide help where needed.

Personal interests

I love spending time with my wife exploring the outdoors, going to new restaurants, trying new activities and traveling. My personal health is especially important to me, so I try to go to the gym regularly. As much as I enjoy going out, I love my time at home as well, watching movies, shows or playing board games.

Ratings and Reviews

About Our Ratings and Reviews

About our Survey

Our physicians and advanced practice clinicians (CRNPs and PA-Cs) are among the nation's best. That's why we show you patient satisfaction ratings and comments so you can read about and get to know our providers through the eyes of their patients.

To ensure our ratings and comments come only from verified patients, we work with NRC Health, a third-party organization. NRC Health sends patient satisfaction surveys on LVPG's behalf following an office visit or procedure. They ask patients about their impression of the health care provider and the doctor's or advanced practice clinician's communication skills.

What is included in the star rating?

Star ratings are based on a scale of 1-5 stars, 5 being the best. The rating includes responses to these provider-related questions:

  1. Physician Communication Questions
    1. Did this provider give you enough information about your health and treatment?
    2. Did this provider give you easy to understand information about your health questions and concerns?
    3. Did this provider listen carefully to you?
    4. Did this provider seem to know your medical history?
    5. Did you trust this provider with your care?
  2. Overall Provider Rating Question
    1. Using any number from 0 to 10, where 0 is the worst provider possible and 10 is the best provider possible, what number would you use to rate this provider?

Why don't all doctors or advanced practice clinicians have a rating?

In order to have enough data to measure and compare, a health care provider must have at least 30 completed patient satisfaction surveys. Surveys are included for a period of 12 months from submission.
