    Best Dentist I have ever seen, she explains everything in great detail.  Her office is comfortable and relaxing.  Her treatment for my teeth has been nothing short of fantastic and I highly recommend her for everyone.  I deathly dread going to the dentist but her professionalism and fantastic treatment makes it a pleasurable visit.

    Dr. Liethen is the BEST dentist. She does fabulous work, is respectful and kind to all of us who are terrified of the dentist, has a bright and spotless office, and truly has the friendliest and most competent staff I have ever met. I was able to meet her and the staff before I made my first appointment and knew I was in good hands. Since then, Dr. Liethen has repaired a lot of old dental work and made my teeth look good again! I actually look forward to seeing everyone at the office when I need routine dental work done. I give Dr. Liethen my highest recommendation. I can’t imagine calling anyone else my dentist.

    Dr. Liethen has been my family dentist for 12 years. Through her competence she has saved my teeth without putting me through costly dental procedures. If you need a specialist, she recommends the best. I’ve sent many men and women to her and every one has profusely thanked me for sending them to such an excellent dentist. Not only is Dr. Liethen charming and professional, her loyal office staff is equally competent and caring. I have always been grateful to have access to such quality dental care right here in our village.
