Care Philosophy

This content was provided by Dr. Sun "My top priority in the first visit is to establish an accurate diagnosis.  A major part of my approach is taking a careful history including hearing the patient's words and recognizing his/her nonverbal clues. I examine the patient to confirm or rule out my suspicions. 

I use endoscopy (a thin flexible camera that can be inserted to view the nose and throat) when needed to investigate areas not visible on a typical physical exam. Endoscopy gives immediate information without radiation exposure. Of course, I do order scans when necessary, but never to substitute for a careful exam.

I tailor treatments individually for each patient. . I am mindful that patient's have out of pocket costs. I offer generics and nonsurgical treatments whenever possible.  Every patient will have a different treatment that is best suited for her/him.

We want the simplest, quickest, least expensive, least invasive, lowest risk, most effective treatment.  Obviously, no one treatment is going to fit all of those criteria, so my rule is that each patient choose his or her treatment with my nonjugdemental guidance.  My goal is to have as many as may patients achieve their desire outcomes by succeeding one patient at a time."

Patient Comments (6)

I saw Dr. Sun as a second opinion and was very impressed. The first thing he did was scope me so he could see what was really going on and what the best options are. Whereas the other ENT I had seen previously just wanted to have me do expensive testing and take more unnecessary medications. Dr....more

I have asked many different doctors about my condition, and well they all provided me with a quick glance and said it was normal. But it started to take a toll on my life so I decided to schedule an appointment with Dr. Sun. He was a funny and sweet guy, very easy to talk too. Definitely made me...more

I really like Dr. Sun because he is professional, courteous and kind. He diagnosed my cancer and then operated on me twice and basically saved my face, which is very important to me (doh!). The office hours are so flexible and they work very hard to get you seen, even on short notice.

I didn't have to wait long before I got called back to the examination room. I was given an exam with an explanation as to what he was doing and why which put...more
