    Patient Experience

    I have been a patient of Dr. Rayhan for over 20 years. He is an amazing and caring doctor who has always put my best interest first. He has done full mouth implants on me and they all have been absolutely painless and flawless. He gives painless injections like no other dentist. He should really teach other dentists how to give injections. I highly recommend him. -Google

    My experience at Clock Tower Dental Associates was first class. I needed a tooth pulled followed by a dental implant and the process was as seem less and painless as possible. Dr. Kelley gave me a thorough explanation of the procedure start to finish so I knew exactly what was going to happen and how long the process would take. Now that the procedure is complete a can’t tell I’ve had anything done. I would highly recommend Clock Tower Dental Associates to anyone in search of a knowledgeable, experienced, and friendly dental team. -Google

    I have been going to doctor Rayhan for years now. I cannot even express my respect and love for this doctor. I was so afraid of going to the dentist for many years. I am never afraid anymore because doctor Rayhan is so compassionate and gentle I literally rarely have any pain after some pretty big procedures that I have had. He is top-notch and if you're afraid, don't be his great with the needle, LOL. I love you doctor Rayhan you know how much I do. You have been nothing but amazing with me. I will always speak highly of you and your skills. Of course, the staff is also wonderful, compassionate and amazing. I'm not afraid of the dentist anymore Love you all. -Google

    WOW! This was more than a game changer, it has been a life changer. I had visited a few places, but none had given me the confidence and assurance that Clock Tower Dental showed. So many years of fear, pain, and embarrassment were erased once the work was done. In only a few hours they changed my life drastically, just like they have assured me. The transformation has been short of a miracle. The team at Clock Tower Dental has been amazing. A great job indeed, thank you! -Google

    It is with a great pleasure that we write this review . Dr Rayan is our miracle worker. All the work he does for us is always to perfection. He is super patient, kind, and caring!

    The best dentist in the United States. I live in Los Angeles and I go to him every six months. Dr. Rayhan is the most caring and knowledge and up to date person. I went to another doctor, before and they wanted to pull 2 of my teeth out but when I came to doctor Ramin Rayhan, he saved my teeth. I will never go to anyone else. His staff is very nice and friendly. -Google

    I have been going to Clocktower for over ten years, and absolutely love it! The dentists are great, the staff is friendly, and most importantly, they take great care of my teeth. I have everything done there - from bi-annual cleanings, to a tooth extraction and an implant. I love that the office keeps up with the latest dental technology. I have never had a bad experience, and I don't ever expect to have one either. -Google

    Dr. Rayhan is by far the best dentist I have had in a very long time. He was thoughtful and considerate with all of my concerns. I have a severe fear of sitting in a dental chair and he eased my fears. I had 2 implants done and I was finished within 40 minutes. I was able to go to work the very next day and was fine. If I could give him 10 stars I would he is a class act!! -Google

    While vacationing in Florida I got into a car accident and my two front teeth broke. After getting emergency root canals over there I decided I would get veneers when I returned to NYC. Choosing Clocktower Dental was definitely NOT a mistake. The staff is polite and helpful and Dr. Rayhan is amazing. He makes you feel comfortable and does incredible work. Nobody even knows I have veneers. I recommend Clock tower to everyone who will listen. -Google
