Outstanding professionalism, care and concern, communication skills and sincere interest in me as a person. My concern was a probable hernia and was confirmed by my provider and we discussed surgery options as to a date.

June 15, 2018 7:00 PM

Dr. Iwanicki performed the abdominal part of the surgical procedure when I had to have surgery to place a shunt in my head after a brain aneurysm. I had been having quite a bit of pain in my abdomen area following the surgery, so I followed up with Dr. Iwanicki. While he was very kind and listened to me, he did not seem to have a very good explanation why I would still be having pain in that area after 6 weeks, so that was somewhat disappointing.
