    If I could give more than 5 stars I would! Dr. Winckler and his staff were amazing! I was looking…read morefor a dentist who could help me with my cosmetic concerns for my smile and I came across Dr. Winckler because of his great reviews. My consultation was so thorough. I could tell that he truly cared and understood what I was looking for. My appointment got postponed because of COVID, and once they opened he scheduled me right away. When I arrived they took my temperature and went above and beyond to follow all precautions for sanitation and safety. I attached a before and after pic of my transformation, it was truly life changing for me and haven't stopped smiling since I left the office. Thanks again to Dr. Winckler and his staff!

    I had been going to my previous dentist for years and during that time recommended several people…read moreto him. These were people like myself who disliked and were afraid of dentists and walked out of his office loving him. Recently he retired and I've tried 3 different dentists which could not compare or even come close. I've had dental issues for years and needed a dentist who wasn't eager to pull teeth or just fix an issue without trying to find the root cause. Dr Winckler came highly recommended and I was told was "the best dentist" around. After my first visit with him I totally agree. He took the time to explain his approach and I was impressed. I left his office feeling I have finally found another dentist I could feel comfortable with and once again put my trust in. I highly recommend Dr Winckler - at least set up time to consult with him as I am confident you will not be disappointed!

    I had recently switched to this dentist and had an emergency in August when my front tooth broke…read more The first time I called the office, I got voicemail, so I left a message with details on how to reach me and what I was looking for. I didn't hear back. So, I called again and left another voicemail. This time, I got a callback, but I was in a meeting - thus began the game of phone tag. For every three messages I left (including desperate ones saying "I would like to set an appointment for this day - can you fit me in and let me know what time I should be there?"), I got one call back. I thought I was crazy, so I checked their website at: http://www.advanceddentalconcepts.net/ which clearly said they had office hours Monday - Friday. (Still does at the time of this review) Finally, three weeks later, I managed to reach someone instead of the blasted voicemail. The staff told me that their hours had been reduced to Tuesdays and Thursdays only, and that the earliest they could see me would be in the middle of December. I explained my situation, including the frustration with simply setting an appointment, and pleaded to get an earlier appointment. I was denied. Not only was I disappointed in the lack of compassion for a person wandering in public with half a front tooth, but also for the lack of professionalism. Simple business sense dictates that you answer the phone when a customer calls. I felt like I was putting them out for trying to give them business. Only use this dentist if you want to wait months for a simple appointment and if you prefer to speak to a voicemail machine. I ended up calling my insurance company and changing to a new dentist who saw me within a week and has staff who answer the phone. (Responsive, compassionate ones do exist - just not at this office.)
