Diamond Bar Dental

I had a wonderful experience with Dr. T and his team. They are very thorough, professional, and clearly know what they’re doing. I always feel comfortable and confident in their care. They also do an excellent job explaining insurance coverage and treatment costs before starting any services, which I really appreciate. Everything feels organized and runs very smoothly. I am set here and found my place. Highly recommend!

Dr John is amazing. From fillings to crown to laser treatment repairing my gum, he is precise, quick and professional. I’m very thankful to have him as my dentist, just wish I had found him sooner. Samantha, the hygienist, is also great. I used to stress over deep cleaning, but not with Samantha. She is gentle and she informs me of every step, which helps me feel at ease.

This place and the staff is simply amazing 👏!!! Sandra, Samantha, Carla I've meet are just awesome 👌 Dr. Tchaboukian is probably the best dentist I've ever seen. He's an amazing Dentist. Very professional and truly cares for his patients. The office & facility is very clean and welcoming. If you are looking for a new dentists come to this place. Switch now! Diamond Bar dental the best dental practice!!! I'm so grateful I found this place 🙏

Dr. John and all of his staff are amazing. They are all very welcoming and accommodating. I got quite a few fillings done and Dr John made sure I was comfortable. Dr John is very friendly and does an amazing job. He took out some of my nasty cracked silver fillings from when I was like 10 years old and replaced them with white ones. This has boosted my self esteem and confidence and it was nice that he offered to do such a thing for me. Samantha the dental hygienist is amazing too. She did a deep cleaning for me and ensured it was a painless process. I was terrified of going into the dentist since I hadn’t been in 10 years and all of the staff made this such a wonderful process. I’m actually excited to keep going back to Dr John and staff for any dental needs I need throughout my life. Thank you all! You are all so appreciated!

I give this place a 10/10 been going to Dr John for over two years hands down the best dentist , his work is amazing !! Amazing doctor explains everything very caring great personality ! And Sam the hygienist she’s the best , great personality (:

This is honestly one of the best dentist offices I’ve ever been a patient at. Samantha is amazing!! She pushed her lunch back just to make sure I got my teeth cleaned. She is also very smart, she informed me everything she was doing and what exactly it meant. Also the dentist John is very sweet and informative. He took photos of my mouth and showed me exactly what his areas of concerns are. Overall this whole dentist office is clean, thorough, and friendly. They know how to do their job correctly and treat their customers like family.

I’ve been coming to see Dr. John since 2020, despite living a couple counties over. He takes great pride in what he does, and for good reason. The quality of his work is top tier. Best dentist I’ve ever had - I can’t recommend him enough! The hygienist Sam has been quick and efficient, not to mention delicate while taking X-Rays. Maria at the front desk is personable and accommodating! Big fan of this office.
