The best of the best, like that of Dr. Vissor. I have complete confidence in her surgical expertise. I’m in amazement at how easy this surgery has been, and with little pain. I would recommend her highly to anyone needing hiatal hernia repair.
She was very knowledgeable and was able to explain my case in details that I was able to understand. I highly recommend her and I feel very safe with her.
Very patient great listener and makes you fell very comfortable! Great doctor!!
Best health facility I have ever been to. Efficient, friendly, clean, professional, modern, easy, fast -- unlimited adjectives available.
Wonderful experience with Dr. Hahn
I thought that the visit with Dr. Hawn was excellent.
Just wanted to clarify that Dr Hawn, joined right when she was supposed to join... As scheduled I was suppose to talk to her Nurse first, and then talk to Dr. Hawn. After talking to her nurse I had to wait just a few seconds, ie, nothing. (I misunderstood the question and timed it from the beginning of the connection with the nurse). Everyone was extremely punctual!! I'm extremely happy with Dr. Hawn and all her team, absolutely everyone in her team!!! Again, maybe there was a misunderstanding on my part regarding the question about Dr. Hawn joining a few minutes later... She was on time... I had to wait just a few seconds, ie. No waiting time at all. Please change my answer to that question to just a few seconds (instead of 5 minutes).
Mary was very direct, informative and clear with her diagnosis and I’m very thankful for that!!!

Her personality is very direct and to the point which I appreciate, when it comes to my health I don't need rainbows and butterflies, I just want the facts and Dr. Hawn seems to be a straigh shooter clearly identifying the risks of my proceedure, what to expect during the procedure and my recovery. I wish we had more Doctors/surgeons like her.

They were on time very nice & professional.
Very good.
I have high confidence in the treatment and advice I received from Mary Hawn.
Dr. Hawn provided an excellent second opinion for me.
I was given very little information about what to expect with the surgery, how it was going to be done, i.e. Why I had 10 incisions, what to expect post surgery, that it would be the most painful surgery I have ever had! The hernia pain was worse after surgery, still hard and swollen, and still is! The stab wounds are still painful and red, although I have had them checked for infection by my PCP. Dr. Hawn answered my concerns on the last visit., but I should have been told during the first visit to alleviate my worries post surgery.
I would like to have seen my CT scan & examined it with doctor answering my questions.
