I was worried and nervous as I didn't know what was wrong. Dr. Sedeyn explained everything so well and answered any question I had. He also explained what I could expect in the future. I can say only wonderful things about my experience!

This is the first time I saw Dr Sedeyn and I really didn't expect him to do anything but just a consult on my first visit but he saw that my issue needed to be taken care of ASAP and said let's do this procedure today and got me taken care of. He was kind, courteous, knowledgeable, and funny. He made the feel very comfortable before, during, and after the procedure and I'm very thankful I was referred to him.

Seeing a new provider makes me nervous. However Dr. Sedeyn made me feel comfortable and explained things in a way that was easy to understand. He has great bedside manner and seems like a great provider. 10/10 will definitely recommend!
