Superb experience
Dr. Koenen provided excellent dental treatment and repair of a failing existing filling. He is a very easy to communicate with and listens to his patients needs and concerns with great acumen. I highly recommend him.

Very Professional. As Always.
Staff was courteous, on time and efficient. Hygienist (Julie) was personable, remembered me personally and my family. She talked with me about general oral Heath care, but I didn't feel lectured. And best of all, Mark Koenen DDS didn't try to "find" work to be done. It was as positive of an experience that "going to the dentist" could be.

Always friendly, open and honest.
Dr Koenen has been our dentist for over 19 years and we have always appreciated his directness and genuine interest. His staff is equally as good. We are not moving to Arizona and will have to find someone of equal quality and concern. Blessings to all.

Awesome, as always!
Dr. Koenen and his staff are always professional, yet very personable. I have full confidence in Dr. Koenen's expertise and that of the hygeinists, as well. I have had nothing but positive experiences (as positive as a dental visit can be!) with his office over the many years. His secretary goes out of her way to work with you when needing to change an appointment and work with your schedule.
