John McRae
Dr. Leoni is an excellent dentist. He took the time to show me the x-rays and thoroughly explain what was wrong with my tooth and how to repair it. I felt no pain and was very comfortable while he worked. Now my tooth looks and feels perfect. The office was comfortable and relaxing. I’ve never seen an office so filled with natural light. The entire staff were really nice and very efficient.
Response from the owner:Thank you so much John for the great review! We do our best to provide an excellent dental experience and really appreciate you sharing your experience at Coastline Dental! We look forward to continually taking great care of your dental needs!
Matt Capelouto
I’ve been going to Coastline Dental for a while now, and Dr. Leoni is honestly one of the best. He really knows what he’s doing and takes the time to explain things in a way that makes sense. You never feel rushed, and you can tell he actually cares about his patients.

The staff is super friendly, the office is clean and comfortable, and I always feel well taken care of. Whether it’s a cleaning or something more involved, I’ve always had a great experience. Highly recommend Dr. Leoni and his team if you're looking for a solid, trustworthy dentist.

Dr. Leone is a new dentist for me, but I really like his chair, side demeanor . Really nice guy and his wife works in the office as well so it's like a family business but it's really really nice. Five

Digna Legaspi
I just got my crown today and Dr Leoni and his assistant Keren did a great job fixing my old tooth. I was so happy I got my crown the same day. They use high tech stuff. I didn't have to get the yucky impression.I was nervous before this appointment but they put me at ease and even offered me a blanket. The location is great, parking is free and it is right next to the new outdoor mall, Riverstreet. The facility is really clean, they even have refreshments at the front desk and friendly front office staff who greeted me right away when I walked in.
Response from the owner:Thank you Digna for the fantastic review! We really appreciate the positive experience you have shared and look forward to continually taking great care of you dental needs. We love what we do and thank you for complimenting us!

Jan Nelson
I had been a patient of Dr Scott Lamming for 39 years. He and his staff have always been informative, gentle and caring.
I am 72 years old and continue to receive compliments on my smile.
I was happy to meet with Dr Leoini a year ago.
It’s currently Dr Leoni’s first anniversary in this practice. He’s a perfect replacement, and the hygienists have all stayed on.
I still enjoy going to my Dentist.
Response from the owner:Your compliment is greatly appreciated Jan! We thank you for your thoughtful review and your continual trust in us!
Jeffrey Stern
Started coming here about a year ago after looking for a new Dentist. Dr. Leoni and staff are all super friendly and kind. They do everything to make you comfortable. The hygienists are the most gentle I have ever had and I never come out feeling like my mouth has been attacked. I really appreciate their technique and care. They also work with insurance without making it a problem-not every place is as helpful with insurance. This is my new go to Dentist as long as I live in the area.
Response from the owner:Thank you so much Jeffrey for your very kind review! We really appreciate it and look forward to continually taking great care of your dental needs!
