They are super nice and do great work. And since I pay out of pocket, their prices are pretty reasonable.

I couldnt have found another dentist more caring and personable. She took the time to listen to my concerns, was very professional. No wait times and her staff was GREAT! Tammy is the best. Soo proud to have them in Granite City!

I would recommend Dr. Donna Porterfield to anyone! I was actually dreading finding a new dentist, especially after I realized that I needed a lot of work on my teeth. She was very compassionate to my situation. For me that goes a long way and I just love her staff Tami and Lyndsie. They make a great team and they make you feel comfortable!

Great experience. Donna has been the only dentist to be able to give me a shot without it hurting. Lyndsie does a great job cleaning my teeth also. They make it more enjoyable to go to the dentist.

found that she is personable and the staff is a hoot. I actually guffawed through my latest cleaning. She makes you feel comfortable. It has been one of the most positive experiences with a dentist I have ever had.
