They have been amazing. I originally came to the office for pre surgical work and they did a phenomenal job. Since then any time I needed a check up or consult they have been available and helpful. Highly recommend.

I recently met with Dr. Roberts and his staff for my initial consultation regarding Invisalign after having had three previous orthodontic consults. I first met with Lisa who was very knowledgeable about the complicated world of insurance. She was patient and kind as she answered my many questions and explained the logistics in detail. Dr. Roberts then met with me and took a great deal of his time examining my teeth and discussing my possible treatment options. It was great to feel so seen and listened to. Dr. Roberts, Lisa, and the rest of his staff were honest and genuine- I am looking forward to my results!

I am having a wonderful experience with Dr. Roberts and the entire team! It is truly a pleasure to go back every time, everyone is kind, funny and professional. Besides the orthodontic treatment, I also needed jaw surgery, so Dr. Roberts referred me to an excellent surgeon. I am very happy with the results of the procedure, my bite was almost perfect right after surgery, which is the result of the careful pre-op work of Dr. Roberts and the precision of my surgeon. Only minor orthodontic adjustments are needed now and I have a very nice smile already, for the first time in my life! I referred Dr. Roberts to a colleague of mine, and she is also very satisfied!
