I am very happy they worked me in. I've been having bad headaches for awhile and trouble breathing. Go figure I needed sinus surgery which I wasn't too thrilled about. The surgery was not as bad as I expected and Dr. Zwack was nice and patient about my 5 million questions lol! Im writing this because my headaches and breathing are 100% better thanks to him!

Dr. Zwack just put tubes in both of my kids ears. He was great with the kids (they loved him) and I really appreciated how he worked me in.

Zwack and staff unfriendly/cold. Didn't get back to me with test results for a week even though they were available. I had to ask them. No follow up. Didn't even catch that I have a deviated septum. Just don't seem very professional. Handed me off to another specialty without thorough follow up of my condition.

Good solid doctor....very confident yet he suggested I get a second opinion. I did and had Dr. Zwack do my ear surgery. My surgery outcome was better than expected. that's why Im position this.

I went to see this Doctor after my granddaughter received tubes from him. I had a major ear problem and I was worried I would needed to be operated on. Turns out I did. My friend's daughter works in the operating room at New Hanover and said Dr. Zwack is the fastest and best surgeon in the area. He finished my surgery early ( my family was appreciative of that!) and was very attentive to my after surgery needs. I say go to him for surgery if you need it.

Dr. Zwack is an impressive provider. I was referred by Chapel Hill. One because I live in Wilmington and two, because I was told he was the best ENT in the area. He has proven himself for my primary problem so I have now gone back to him for other ear issues. He's always on time and his staff is always friendly and professional. I tell all my family and friends to use him.

Today, 03/15/2016, was my second appointment with Dr. Zwack and very likely my last. He was very arrogant and spoke to me in a harsh condescending manner. He even insinuated that my visit was unnecessary and was not necessary. never again.

First time ever breaking down and going to an ENT. In the last 10 years I've begun getting severe sinus infections with every minor cold. Felt it was time to assure I didn't have something significant going on in my sinus'. Without even looking at me Zwak said you have a cold, you're normal, and it's viral so there's no medication that will help. I didn't go to a sinus specialist to receive the diagnosis before the examination. Didn't even look at my sinus! Never again!
