Dr. Gunst was wonderful! I have had consultations with several surgeons, and from the moment Dr. Gunst walked in, my husband and I were both sure that he was the one to go with. He was in no hurry to get to the next patient, very kind, compassionate and patient with all of our questions, fully explained my situation and his recommended treatment, timeline for recovery, etc. I have an inguinal hernia and do not want to use synthetic mesh, and he didn't even hesitate or try and persuade me to consider other options. He is clearly very familiar and comfortable with many different procedures and options, and instantly had the perfect recommendation for me. We were so reassured by the whole visit experience that we scheduled surgery before leaving, and I have already made a recommendation to a friend as well.

09/27/2025

I have already recommended Dr. Gunst and his team to a friend who has a similar hernia. Shout out to Olivia, his surgical coordinator-she is a doll! She is so cheerful and bubbly, easy to access, compassionate, a good listener, and quick to help with questions or concerns, even personally tracking down some information I couldn't get from the hospital. Her helpfulness has just confirmed over and over that this is the best team to choose. Thank you, Olivia!

09/27/2025

Everyone I was in contact with-from scheduling the consult to scheduling surgery-has been very courteous, professional, easy to reach, and responsive.
