I love everything about this office! Dr Bob is always upbeat and smiling, as well as his staff. You can tell that they all work well together and help each other out, as well as accommodating any concern I had. I worked in a dental office for over 20+ years and it’s nice to see such cohesion. On top of that, I am thrilled with the results of wearing my Clarity aligners after only 6 months. I must say though it can be a tad painful/uncomfortable at times, but it’s so worth it. I had the metal braces 50 years ago, when I was 11-12 years old but my teeth shifted so much I just had to do something. After much research I decided on Dr Bob and am so glad I did. Thanks to everyone who works there for being so helpful!
