Thank you Sarah! for doing an amazing job on my cleaning € my teeth feel fresh and cleanie…read moreThe girls in the front are amazing, warm greetings and always a smile on their face, they helped me out a lot with my finance and they went over with me on how my insurance works. Don't get me wrong mostly their reviews are negative about finances and billing and insurance but we have to realize that insurance makes you think they cover everything but they don't unfortunately. And if you really want the best for your self than yes we have to pay to get the best Quality work done, just like you would for your car or your house. Anyways I was able to get my stuff taken care of today and I just have to say to their assistant Mariana, thank you for sharing some stories with me, you made my visit more comfortable and enjoyable, believe it or not I am very much terrified of being in the dental office. Dr. Shalaby, thank you for exampling and educating me on what needs to be taken care of. In my experience most dentist just tell you what the treatment will be and get moving on it but some don't take the time to educate or explain and that really showed me how your care for your patients. I recommend this place because if your looking for a cleaner mouth and a welcoming staff and a Dr who is very Conservative and very detailed in his work and that actually care for his patients than this is the place for you. Thank you again everyone.

I have been coming to Dana Point Smiles for a couple years and my experience from the front desk,…read moreto Sara getting teeth cleanings to Dr Shalaby himself is superb. They make the office as comfortable as possible and Dr Shalaby is a master Dentist. I highly recommend them if you want to take care of your teeth with the best office possible experience.

Beware Dr. Vashi is fraudulent! His dental work is subpar as he uses fillings to cover up dental…read moreissues rather than repair what is needed, And might I say that your fillings will most likely eventually fall out as two of mine did. I then realized that I have a very decayed tooth underneath one of the fillings that fell off. My son Just came from another dentist today who advised that the dentist who gave him his filling went way too close to the nerve and caused an infection and loose tooth over time. He also charged me entirely upfront for my Invisalign and would not give me all of my trays upfront. He left his previous office and did not complete the Invisalign process or send me my remaining Trays. Needless to say my teeth moved out of place again since I did not finish the tray process.. However he did continue to reach out to me right when he left his previous office for additional payments on additional work that he started and did not complete. At the time these issues were not apparent so I paid him directly for work he did not complete,

Dr. Vashi seemed nice when I met him but I'm thoroughly disgusted at the apathetic attitude of his…read moreoffice. I was told that I needed deep cleaning and just wanted a copy of my X-rays and exam results so I could ask Insurance if it was covered or even get a second opinion. I went to their office in April 2016, it's now almost sept and I still haven't got my results. I have called their office numerous times and left multiple voicemails. I have even spoken 4 times to the front office person who keeps telling me that they will email it to me "today", but that day hasn't not come since April. Either the people who work here are thoroughly incompetent or have complete disregard for the customer's time or needs. Either way, given my experience dealing with the staff here, there is no way I would recommend this office or dentist. Complete waste of time and pathetic customer service.

Our son just had his braces removed and we couldn't be happier with the results. His smile is…read moreabsolutely perfect! Dr. Sayed and the entire team made this experience such a positive one from start to finish. The customer service at this office truly goes above and beyond. The two gentlemen at the front office are always welcoming, organized, and incredibly helpful. Every visit felt easy and stress-free because they were so on top of everything. Dr. Sayed's support staff is also amazing--professional, friendly, and great with kids. They always took the time to explain what they were doing and made sure our son felt comfortable during every appointment. We are so grateful for the care and attention they gave throughout the whole process. If you're looking for an orthodontist who delivers incredible results with outstanding service, I highly recommend Dr. Sayed and his team!

Dr Sayed has been wonderful with my eldest boy treating him with expanders to help create more…read moreroom, along with opening up his sinuses and shaping his palette. He has experienced so many ear infections in the past and since he's had expanders and we've opened things up they have gone away. Our Son has tolerated the expanders very well and has been wearing them all of the time with no issues. They are not supposed to be cosmetic like braces but making more room has definitely helped to straighten things up anyway. We are about to start with our youngest now and I have no doubt that his sinus congestion issues will be significantly improved with the expanders. Dr Sayed is so friendly, calm and nice to the kids (and parents). He seems to genuinely care about the well being of your kids and is passionate about how an Orthodentist can help improve your child's quality of life long-term (helping with snoring and other problems due to tight nasal passages). Both of my kids don't mind going in to their appointments at all which I think says it all. He and Shawn will work with you to help keep your kids on the same schedule and avoid unnecessary driving back and forth. Shawn is wonderful also and so helpful/accommodating. He is organized and so friendly as well. I would recommend them to anyone.

We cannot say enough amazing things about this dental office!

Not only that, but they went above and beyond to arrange additional appointments for each of us to ensure everything was perfect before our wedding day. From the moment we walked in, we felt so well taken care of. Annie at the front desk was a complete gem, making the scheduling process seamless and stress-free. Anne did an incredible job with our cleanings--painless, thorough, and so comforting. Shannon was excellent with our x-rays, and Dr. John Rezaei was nothing short of AMAZING. He took the time to explain everything, made us feel at ease, and delivered truly top-notch care. We're so glad we trusted the other glowing reviews, and I hope this one encourages you to do the same. My fiancé loved this place so much that he's already decided to make the drive from LA to Dana Point for any dental needs in the future! This is hands down the best dental office we've ever been to. Thank you so much to the entire team--you made such a difference for us during a chaotic time, and we are so grateful!
