Karen Moran-Smith

As an older adult, 61, I was a nervous wreck about getting braces. Dr. Bob and his wonderful team made me so comfortable each and every visit. The eleven months flew by. I'm very happy with my smile now!

Justine MacKechnie

The office is so clean and comfortable. All of the people who work here with Dr. Bob are friendly, caring and work quickly! When my son has had a broken brace, or needs to get in, they work hard to accommodate our schedule. If you are looking for an orthodontist look no further.

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!

Just over a year with clear aligners and I can’t recommend Dr. Bob and his team enough! Everyone was so lovely and accommodating, and my teeth look just stellar! Big BIG thank you to everyone there! I’m legitimately going to miss my regular visits with them now that I’m done with treatment.
