I have been visiting this office for about 3 years now and they recently changed their office staff for the better! The new office manager Ashley is so kind and made me feel comfortable right away! She listened to all my concerns and took immediate action! Paola, the dental hygienist is the best!! She works with such great care and efficiency! I also met the new dentist and he was also informative and listened to my concerns! I’m very pleased with the new staff and definitely recommend this location!! The care and empathy they provide are top notch! Plus the environment is very clean and calm!
