Very reassuring. Explained everything well. Took great care of me surgically and was thoughtful in helping me plan out the treatment process with my family commitments.

Dr. Ahn provided exceptional care from day one. After receiving a DCIS diagnosis, Dr. Ahn took the time to review my mammograms and biopsy with me. She thoroughly reviewed all treatment options and listened to my questions and concerns. She is direct and compassionate. I felt very comfortable knowing she was in my corner during surgery.

Impressed by Dr Anh and her staff. Surgery went well, I recovered easily and she was up to date on current research and took the time to discuss at length with me and my daughters. She is an excellent surgeon with a great reputation according to my oncologist and several friends. I highly recommend Dr. Anh

My experience with Dr Ahn was positive. While she had protocols that prevented some of my out of the box requests, i found her capable of listening carefully, never rushed, and willing to investigate my requests.

She was unprepared, did not have previous mammograms available. She adamant about cancer even though not diagnosed. No help just said I'm not your mother I can't make you get a biopsy! Not progressive, and would not order ultrasound until I have another mammogram even though I had one in Jy. Said to have another mammogram so I could prove her and radiologist wrong.

Very unprofessional. She had no answers for my questions. I was worried about my health but she hardly had time to talk to me. He was not able to diagnose me correctly and ended up sending me to a specialist in the same group. Both Mary Ahn and Gheta Karnik were giving me a run around. Both were saying the same thing and I had to visit both of them at all of my appointments. Insurance was surprised also. My inflammation escalated a I ended up going to someone else.
