*Doctor Yoon is an excellent, I couldn't care asked for a better doctor.
The provider did not take notes at the time, but perhaps he did not want to be distracted by our discussion & I respect and appreciate that.
My husband went to *Dr. Yoon & we were so pleased with his work & care that is why I waited to see him instead of my regular gastrologist at another facility.
*Dr. Yoon was very thorough in explaining my medical problem to me.
I only met *Dr. Yoon once.

Physician Bio

As a physician my practice philosophy is simply, “no one knows you better than you do.” That’s 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.

In my leisure time, my greatest source of enjoyment is spending time with my wife and two young daughters.
