Very professional and friendly staff! Everyone was wonderful! They were very thorough with everything and I was only there for a consultation, complementary at that! Dr. Koen was so very nice and extremely helpful. The entire visit was a great experience. Needless to say I will be trusting them with my smile! 😊
