Janel Kluck

“I was more than pleased with the results I received after having the ZOOM teeth whitening treatment done by Dr. Prehn. The entire process from start to finish was professionally completed. I wish I would have received this treatment a year ago. The best part, I receive compliments about my teeth on a weekly basis and that makes me smile more!”

“Dear Fred, I had a dentist appointment this morning…it was fine, nothing special. It made me realize how much I miss being your patient. You have an exceptional practice and we miss it(image someone missing their dentist!). Your innovative care, culture of staying on the cutting edge, strong and friendly team combined with true compassion is extraordinary. You helped me with issues that have had major positive impact on my oral, dental and overall health. I always appreciated your candor, transparency and good humor as well. Fred…You are a superstar in your practice, in the community… and in my eyes. If I never get there again… Thank you for being special… and all the care you provided us!”

Bob Erickson

“I needed major work done and wanted a true professional. Checked out a couple of dentists and was not impressed. Finally, I discovered Dr. Prehn and found him and his staff well organized, accurate, friendly and extremely professional. Dr. Prehn is an excellent dentist, he knows what he is very good at and also knows where to send patients for root canals and implants. Dr. Prehn carefully examined my teeth and made an appointment for presentation of a treatment plan. He explained treatment options and costs in detail and allowed me to decide for myself. The restorative treatment took a little bit more than a year. I am very happy with the results and would recommend Prehn Dental to anyone looking for a competent dentist who cares about his patients. My wife will be next in line.”

“Before my implant procedure, my mouth, at times, had sore spots. Eating was difficult. Now I’m comfortable and confident. Implants were the way to go for me. Well worth the investment.”

“Having my front teeth reshaped has made my smile even prettier. The time and expense were minimal, it was completely painless and the staff at Prehn Dental was very accommodating”

Rebecca Kermitz

Wausau, WI

“I have had extensive dental work done (implants & crowns). From the very beginning of the implant procedure, Dr. Prehn worked hand in hand with the Oral Surgeon who had recommended him to ensure the end result would be what he had envisioned. For the remaining restructuring, Dr. Prehn again painstakingly took his time to make sure everything was precise, fit well and that I was pleased. I find Dr. Prehn to be a highly experienced, responsible, meticulous and caring dentist. Thank you, Dr. Fred Prehn and your highly professional and caring staff associates. I look forward to a long and continuous relationship. I highly recommend Dr. Fred Prehn and associates for any and all dental procedures.”

Vi Kolbe

“I’ve avoided dentists most of my life due to the discomfort and cost. It became necessary to see “Anyone” last winter, the swelling and pain was horrible enough to go to the emergency room. My sister told me of her dentist and I made the appointment. Since that day my headaches, swelling and acute pain are of the past. Dr. Prehn and his associates did my major problem a great justice. Price and comfort keeps me going back and looking forward to my next appointment. Thank the Lord for Dr. Prehn and all his helpers!”
