Dr. Poettker is the best Dentist I have ever been to, I just loved her! She really took the time to answer my questions and make me feel very comfortable.


I just wanted to thank you for getting me in so quick when I called today. I will definately be back to your office and just wanted to say that Dr. Poettker and her staff were very friendly, caring, and helpful to me.


Dentist Offices are not my favorite place to be, however I just want to let Dr. Poettker and her staff know they make me feel very comfortable and I no longer fear going to the Dentist. The staff is extremely helpful, friendly, and truly make you feel at home. Dr. Poettker has a great office, wonderfull staff, and a warm atmosphere.
