I had an excellent experience at Coastline Dental. The staff was friendly, the office was clean and modern, and everything ran smoothly from start to finish. Dr. Leoni and staff were professional, thorough, and took the time to explain everything clearly. I felt well cared for and confident in the treatment I received. Highly recommend this office for anyone looking for quality dental care.

I absolutely love this dental office! The staff is incredibly friendly and sweet. I always feel comfortable and taken care of from the moment I walk in. The dentist truly took the time to listen to my concerns and made me feel heard, which I really appreciated. My dental work was done right the first time, and I was in and out in great time. Highly recommend!

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!

Shaun Smith
Highly recommend Dr. Leoni and all the staff here. I’ve had my teeth cleaned, x- rays and a filling. Quality job and a very friendly atmosphere here. If you’re looking for a new dentist this is the way to go. Also, my mom worked in the dental field all of her life and this is the dentist shoe goes to. A++

Multiple generations of my family have been coming to this practice for two decades. I even travel from Northern California for my dental appointments so I can stay with the practice. Dr. Leoni is a wonderful and caring dentist. He explains his procedures well and will even fit you in during a dental emergency. His team is also amazing—everyone is nice and consistently provides high quality dental work. I highly recommend Coastline Dental!
