I had a very good experience with Dr. Kortebein and the other doctors during the consaltation and the day of the surgery. They made me feel comfortable when I was anxious and talked me through the procedure as it was happening. I would reccomend this office for wisdom teeth removal.

What a great visit! I was in pain and being referred by my dentist as he could not finish an extraction, my first. He worked on my tooth for an hour and a half and my jaw was traumatized. But you guys finished getting to tooth out and it was fast and painless. I will and have already referred someone to you.

They were helpful and the process was clear and well discussed. Dr Kortebein is a true professional and made me comfortable from the moment I met him through the procedure and in follow up.

I don’t like the Dentist, however, this was the best experience I’ve ever had getting a tooth extracted. The Dr. was very professional, attentive and gentle. The tooth was out and I didn’t even know it. I would recommend them to everyone needing oral surgery!
