Dr Wu was excellent with his listening skills, knowledge, and thoroughness, and empathy, everything you could wish for in a doctor. He had been highly recommended to me by someone who had surgery on her wrist with great results. I came for my shoulder and a second opinion on wrist x-rays. He was able to spot details that the first doctor from the same practice had not noticed or had missed . He also tested everything very thoroughly and listened carefully in order to diagnose . He explained what was going on in my shoulder very clearly even drawing me a diagram . He spent approximately a half hour with me never rushing me even though he had an extremely busy schedule that day with several unexpected emergencies that caused him to run behind . I also brought up several other issues briefly and he referred me to other doctors pointing me in the right direction.
