Care Philosophy

This content was provided by Dr. Yoon "As one of the largest and most respected GI groups in Southern California, we offer highly skilled physicians, the most advanced diagnostic and treatment options, and a patient-centered approach.

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."

Dr. Yoon is very patient and takes time to explain conditions, causes and steps of actions with patients. Excellent bedside manner. Great communication skills with patients go a long way and he knows what he's doing and what he's talking about. I'm very confident being under his medical care.
