I had two teeth that had lengthy dental work done yesterday September 29th at Coastline Dental. The results were great. Absolutely no pain during the procedure or after!!
Thank you!!

Valerie Stocks
I’ve had a wonderful experience at this dental office! The Invisalign process has been smooth and easy to follow, they really take the time to explain everything and make sure you’re comfortable each step of the way.

The waiting area is serene and welcoming, with complimentary refreshments and coffee that make the visit feel more like a relaxing appointment than a typical dental visit.

One moment that really stood out was when my daughter was having a tough time during her cleaning, the staff was so kind and attentive, even offering her a blanket to help her feel more at ease. It made a big difference.

Everyone here is professional, friendly, and genuinely caring. We will be coming back!
Response from the owner:Thank you so much Valerie for the wonderful review! We do genuinely care about our patients and really appreciate you sharing your experiences at our dental office! We look forward to continuously providing you and your family excellent dental care!

I love Dr. Leoni and highly recommend him! His experience is top-notch. He will not submit anything if it is not right. That’s the kind of doctor I want! He truly cares and if it’s not right, he’s going to make it right. He does top notch work correctly and carefully.
