Dental Reviews & Testimonials

5-Star Experiences

“I can’t believe I am saying this, but I had the best time at the dentist! The staff was really nice and personable. They let me watch Grey’s Anatomy during my whole visit. Lol! I felt right at home. Dr. Lewis did a great job explaining everything she was doing as she went along and it put me more at ease. For the first time, I didn’t dread my experience at the dentist. Also, if you go here, ask about the whitening trays!"

Breanne M., McKinney, TX

“Customer service was outstanding! They were considerate of all my concerns and explained the process thoroughly. They also took their time to make sure I wasn’t in any pain or discomfort and when there was discomfort they corrected it immediately. Very friendly & attentive.”

Melody P., Allen, TX

"Do I recommend ASD? Ugh absolutely!! They are so welcoming and truly want to make every patient happy. Just got my crown done and had some bite issues after. After placing a quick call to the office, I was told to come on in. I was in and out in less than 30. This is so vital for a working mom like myself that values her time. So glad I found Dr. Lewis and her office staff.”
