A rare combination; a doctor who really knows his specialty and LISTENS VERY WELL. Doctor Nguyen is such a doctor Arthritis specialist. Any and every time I tried to explain my symptoms to Dr Nguyen, he stopped what he was doing and intently listened. He then used his knowledge to explain in simple terms what those symptoms might mean and how to test, treat, and alleviate those symptoms. With his knowledge, he immediately voiced his suspicion about with my knee. He was the 3rd doctor who I had been to about my knee, and the other two did not lead me to the correct diagnosis. He provided a test plan to verify his suspicion, offered to make extra after-hours time available to be able to test his suspicion, and was ultimately proved correct. My knee is doing better than it has for a year now!
