I like Dr. Masak a lot. I like that he asks me what "I want done", and doesn't just tell me what "he" plans on doing. His staff is amazing, you couldn't ask for friendlier people.
He's helped me to save money as my teeth are not in the greatest condition where others would only try to get me to spend a fortune.

I am so very pleased and delighted with the work Dr . John and his kind , helpful , very competent and professional team have accomplished , with the extreme case i presented to them . i was known to refer to my smile as a gruesome grill , which was unfortunately very accurate. Thankfully Dr John loves a challenge and i 'm delighted to share that he was up for the task and more !!! i'm 64 years young and have "never " had nice teeth , i'll spare the details , however NOW i have an amazing smile and my teeth actually meet / touch on both sides of my mouth for the FIRST time in my life !!!!!!!

The team at “Smile On, Appleton” is kind-natured, courteous, and compassionate. Dr. Massak’s assistants and office staff are understanding, encouraging, and lively. Dr. Massak is exceedingly kind; he gives you all of the options that would work for your individual situation and helps you weigh the cost VS longevity in a manner that truly allows you to steer your plan of care. Dr. Massak is the first dentist I’ve ever had who asked me what my dental concerns were; he steps beyond the immediate care plan to make sure your long-term plan of care is formed to your personal goals and your own

Dr. Masak is the best dentist that I have ever met in my entire life ! He is the only dentist that I trust to work on my teeth. He is very good at listening and answering all of your questions. I like the amount of time he spends explaining everything in great detail, and he has an awesome sense of humor as well. His office staff are extremely friendly too.

I cannot expound enough how wonderful Dr. John Masak and his friendly staff have taken care of me. I have recommended Dr. Masak to many friends and acquaintances who were in search of a good dentist. For those who took my advice and went to Dr. Masak for dental care, had a peasant experience, and thanked me. God Bless and keep up the good work! Until next time, always remember...Jesus Loves you and so does Johnny:)

I've seen a few dentists in my 40 years for emergency visits, Never have I had a dentist that I saw more than once. I found Dr. Masak and I'm keeping him! This guy and his awesome staff know what they are doing I waited too long to find him so I had to have a complete extraction that I wasn't looking forward to, But his team was very educational & professional yet still had a great sense of humor. PAINLESS!!
