Tustin, CA |
Rude, arrogant, he doesn’t know any I don’t believe he is a doctor. Very disappointed experience with follow up visit. He didn't explain clearly what patient’s results and medical conditions were, not a courteous and kind guy at all, lack of manner to patient. I was afraid to ask some questions about the results he seemed to be reluctant to answer any questions that patients might have. He is very unprofessional and horrible doctor. Other reviews are telling the same. I don't recommend him.

This Doctor Ahn is the worst doctor I have ever met and encountered, very unprofessional. I havent done talking to him about my concern and he is walking out of the door already. Not even 5 mins that stayed in the room with me. I really wanted to change doctor, but I have a pending treatment in back, so i cannot cancel the care. I don't recommend this doctor because he is very impolite, not even answering your concern and not even asking what are the care that a patient needs. Maria is Nice.

Dr. Ahn provided me with the worst care and bedside manner that I have ever encountered. I could of changed providers at any given time but I had multiple surgeries in the pipeline which would delay all of them. It was an uphill battle to get any of my medical needs met. Ex. I told the Dr. I wanted an MRI for my back due to long term back pain. He suggests Yoga. MRI comes back L5-S1 bone on bone. I could go on and on. Maria and Gabby run the front office and they are so professional and lovely!
