Patient Ratings & Comments


Comments are gathered from our patient satisfaction surveys.

Dr. Chon easily explains the patients medical problem and inspires patients reaction to follow healthcare related suggestions. I feel extremely comfortable with Dr Chons approach to my diabetes 2 treatment [...].
Dr Chon is an excellent clinician with the best bedside manner! Love him!
I was very impressed with Dr Chon. He took his time to explain things, very pleasant
[...] Dr. Chon was wonderful. he answered my questions, created a treatment plan and explained what I should expect/anticipate. I will highly recommend him. [...] I will need to be seen on a regular basis because my thyroid is not in a remissive state and will be driving almost an hour to get to Dr. Chon's (every 5 weeks), but it will be worth it. Honesty, I would go to him even if I had to pay out of pocket. I think that says quite a bit about the quality of my visit.
Dr. Chon was very thorough with the entire process. Relieved my concern seeing someone who was not recommended.
