Tour Our Dental Office

Exceptional Dentistry is Just What We Do

“A lot of people are saying it, but it’s definitely true: this is literally the best dentist office I have ever been to!! They have superior service and the best staff. My personal favorite part is that everyone is dedicated to making me feel comfortable and educated. Every question I ever have is answered genuinely and honestly. I don’t ever feel like I’m being talked down to. I tell everyone I can that they need to come here.”

Holly G. Las Colinas, TX

“I’ve been visiting Dr. Roy for over 10 years now. He is the best of the best, as is his staff! They are always so personable and kind, and great with children. Their office staff are always so willing to help you in any way that they can. They truly enjoy what they do, and it shows in how they treat you. They are skilled and run a tight ship. I will never go anywhere else!”

Mandy S. Irving, TX

“EVERYONE at this practice is extremely nice. I remember when I first started treatment, I asked Dr. Smith, ‘Why in the heck is everyone around here so happy all the time?’ And he smiled and responded something along the lines of, ‘Well they should be or otherwise they can't work here.' He takes customer service very seriously! I have never had a bad customer service moment ever, in 2.5 years... over the phone or in person!”
