About Eugene J. Yoon

As a physician my practice philosophy is simply, “no one knows you better than you do.” That is why I take the time to get to know my patients. What may work for one patient, may not be right for another; therefore, it is important to listen to the patient. Listening is key to making an accurate diagnosis and finding the solution that works best for the individual.

By offering the latest advancements in diagnostic techniques and treatments, I can provide the most effective and timely care for each patient. I make sure to keep patients fully informed and educated about their medical condition, and work with them to manage their care.

I pride myself in perfecting endoscopic techniques to ensure maximum accuracy and efficacy yet still maintaining safety for my patients. I have a special interest in interventional endoscopy which includes complicated polyp removals, difficult GI bleeding cases, complicated ERCP’s, and stenting within the gastrointestinal tract.

In my leisure time, my greatest source of enjoyment is spending time with my wife and my two young daughters. I have also greatly enjoyed mountain biking around all the trails in Orange County.
