I began seeing Dr. Poppe several years ago on my orthodontist's recommendation after never finding a dentist I really liked. I was immediately impressed: easy access, clean office, incredibly nice staff, and exceptionally knowledgeable hygienists. The hygienists are incredibly thorough, taking photos of areas that need improvement so you can see exactly where your opportunities are. No other hygienist I've been to has done this aside from standard x-rays. Dr. Poppe is incredibly knowledgeable and always makes you feel like you're in excellent care. I completed teeth straightening via clear aligners, and the experience was phenomenal. She guided me through the entire process, including adding two veneers to my lower teeth that made a massive impact on my smile, something clear aligners alone couldn't achieve. The final outcome exceeded my expectations. Hopefully the bulk of my dental work is behind me now. I always look forward to my visits.

I highly recommend this office. Everyone is very friendly and Dr, Poppe spends time explaining my condition to me and my treatment went smoothly. Her injection technique is very good and it did not hurt at all. I look forward to going there again.

I’m sharing my personal experience with this dental office, and unfortunately it was extremely disappointing. I originally visited for a simple cleaning, but I was told that I needed a root canal. They performed the root canal in the clinic instead of referring me to a specialist, and afterward I continued to have pain in that tooth for weeks. I also had a crown done by Dr. Poppi. Before starting the treatment, I told her clearly that I would be moving to Canada. She completed the crown knowing that I was leaving the country soon. When I saw a dentist in Canada six months later, I was shocked to learn that the crown had an opening, was not sealed properly, and left a noticeable gap between the crown and the tooth next to it. Food kept getting trapped in that space, causing constant discomfort. Later on, I saw two other dentists, and both agreed that the crown had been made incorrectly. When I returned to the US after one and a half years and contacted the office, hoping they would take responsibility for their work, they simply told me that I had no warranty because I had moved out of the country. I don’t understand how Dr. Poppi allowed me to leave the clinic with such an obvi

No one likes going to the dentist but this has been the best dentist and staff I have ever had. 😊From the minute you walk in to the minute you leave. Everyone is friendly and listens plus always gets me in for emergencies. I had an emergency this weekend and fell and Dr Poppe is getting me in tomorrow. They make you feel like they genuinely care ❀️ I highly recommend!

Cosmos Dentistry is my favorite place for the dental work. All the staffs are very courteous and friendly. I’ve been their patient for over a decade. The clinic has TV at each chair for the patients to choose a show to watch while the staff work on the patients dental work. The hygienist always does a very thorough job when cleaning my teeth. When she’s done, she will let me know if there’s any area of my teeth that need to pay more attention for cleaning. The dentist, Dr. Poppe is a very warm and care dentist. She cares about her patients and always does her best to work on the dental work for her clients. Every time when I left the dentist office, I just feel SO good because I know my teeth had been very good taken care of. Thank you very much to all the staff of Cosmos Dentistry, You guys just make my smile big & bright. πŸ˜€πŸ™πŸ‘
