Went to Dr Ahn for a trigger finger. He administered a shot of cortisone and it took care of my problem. He has a great bedside manner, very caring, and knowledgeable. Will recommend to anyone who has hand problems.

Dr. Ahn, He's great he has done 3 of my surgeries, He is very good. When I was so scared of the long needles. Until he done it when he gave me my 1st shot and I never felt it, his bedside manner as a doc is great. He's up front and doesn't beat around the truth. He does his job very well.

Did not listen to my concerns. I had a new injury that he dismissed until he did an exam. He was unaware of who I was until the nurse told him he was doing surgery on me. I got nothing for my pain. He ignored my original injury and repeats the same thing and doesn’t address my pain.
