Exceptional service with friendly and caring staff. Fast and efficient. Dr Leoni and his staff are superb!

Amazing! I have used this office for my dental needs over the past several years, and each time, the service has been excellent and met all expectations. Everyone on staff is truly professional. The modern clean office provides fast and efficient service, yet it is very warm and friendly. I highly recommend this office.

Holden Westland
Since Dr. Leoni has taken over the practice, which prior to his leadership was still a very professional and, let's call it a "practical" environment, the overall experience is now far superior with Dr. Leoni and his wonderful, friendly and caring staff. I actually look forward to seeing their smiling faces while they work on the insides of mine lol!
Response from the owner:Holden, your SUPERIOR review of our staff and Dr. Leoni is a joy to read and is why we enjoy what we do..make our patients happy and provide great dental care! We truly appreciate you and always look forward to seeing your smiling face both inside and out lol!! Thank you Holden!

I’ve been visiting this dentistry for a long time, and they’ve always been consistently great. The whole team is professional, friendly, and very organized, and they always make each visit smooth and comfortable.

Elena, the dental hygienist, is awesome. She’s gentle, thorough, and takes the time to explain everything clearly. You can tell she truly cares about her patients and takes pride in her work.

Highly recommend this office to anyone looking for a trustworthy and caring dental team.
Response from the owner:Thank you so much for the GREAT review of our entire team including our awesome hygienist Elena! We really appreciate it and look forward to continually taking the best care of your dental needs!

Kadin Carpenter
I’m so glad I followed my family's recommendation and visited Coastline Dental! The atmosphere is so friendly, and I felt welcomed the second I stepped through the door. Everyone who assisted me was wonderful, but a special shout-out to Elena, my hygienist. She managed to be both incredibly gentle and great to chat with. I’m completely sold on this office—highly recommend Coastline Dental!!

Kameron Madison
I was panicked that I chipped my tooth pretty bad the day before New Year’s Eve… no dentists open for 2 days… I googled and found Coastline restorative dentistry! I looked at reviews and they were all great. I called and they were able to get me in right away. The office was clean and cozy upon entering, the staff was so friendly and attentive! I felt very comfortable! Dr. Leoni was outstanding! Calmest dentist I’ve ever seen! I like things quiet and the dentist and him and his assistant worked quickly but calmly on my tooth! My fixed tooth is gorgeous and I will be making them my new dentists office!!!! So glad I went and I highly recommend going!!!!!
Response from the owner:Thank you so much Kameron for your very thoughtful and outstanding review! We really appreciate it and look forward to continuously providing you with the best dental care!

In August of 2024, we switched practices to Dr. Leoni and we are so happy to be at Coastline Dental for our dental needs. From the reception, Joy is super friendly and helpful. Karen (X-rays) Elena and Natalie (hygienists) Annette ( Doctor assistant) are awesome! Dr. Leoni is kind and gentle and explains what needs to be done. Everyone in this practice is friendly and courteous not to mention they are very high tech and take care of everything for you the same day including crowns!!!! We highly recommend Dr. Leoni’s practice.

I just want to say thank you so much to Dr. Leoni for being the best dentist and always explaining everything so well!

“

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.
