I highly recommend Diamond Bar Dental! I usually get very nervous when it comes to going to the dentist, but not at this place. The dentist and staff truly care about making sure I feel comfortable during every visit. They always take the time to explain what's going on and clearly discuss their recommendations, which helps put me at ease. A special thank you to Bryanna Vasquez, who does such a wonderful job keeping my mouth clean and hydrated during procedures. Her kindness, attention, and care truly make a difference and help me feel comfortable throughout my visits. I'm so happy with my dentist and the entire staff. They are professional, caring, and genuinely amazing. Thank you for always making my experience such a positive one! read more

Been going to this dentist for years. They're always so good and take such good care of their patients. Bryana was especially nice and the doctor is so good. read more

Dr Romi Patel and his staff are nothing short of exceptional. I received the most thorough dental exam I've ever had; the treatment plan was clearly communicated to me and executed well. I fully trust in Dr Patel's abilities and knowledge, and will happily continue to drive the 2 hour drive to his office for long term care. He is absolutely worth it. read more

This is shady dental office. I work in the health care industry, made an appointment for my boy routine every 6 months dental check up, spoke to dr herself and front ent receptionist, that we will pay out of pocket, they quote $89 including X-ray and cleaning, I said this is great price, Today my boy went to appt, they charge $240 , says only X-ray and check without cleaning price will be$89, dental cleaning ( regular) it will cost us $150 !!!! DO NOT HO THIS DENTAL OFFICE IF YOU PAY OUT OF POCKET, they're misleading and won't tell you the exact price until you get surprised by the price you need to pay. I'll spread the words to my coworkers and my other colleagues in the other health dept . So disgusting to deal with them. read more

A huge thanks to Dr. Romi and Bryana for making my first visit so welcoming! Both have excellent bedside manner and make the patient feel at ease. Check in was fast and easy. Bryana was very kind and gentle with taking my X-rays and gave me breaks as needed. Dr. Romi listened to my dental concerns and gave constructive feedback on how to improve my overall dental health. I have been used to dentists that rush and dismiss patient concerns, but here I felt like the team genuinely listened. Office is very clean with great equipment. Location is convenient with plenty of parking. Flexible scheduling for people with non traditional work hours. Overall, I would recommend this office to friends and family. read more

I highly recommend this dental practice for anyone looking for an excellent dental experience. The staff is very friendly and professional, their clinic is beautiful and immaculate, and I felt I was just well taken cared of. My tooth extraction by Dr. Patel and teeth deep cleaning by Kimmie are both awesome and painless. They are simply the best and commend them for their terrific work. read more

Everything went very good everyone is very nice and polite benn going here since the father was the dentist now the son is running the show doing a great job read more

Dr. Romi Patel and the hygienist at this dental practice were very kind and helpful. I was able to get my cavities filled and get a cleaning + fluoride treatment. Thank you Dr. Romi for taking care of my cavities today. I really appreciate your gentle and careful work! read more

This dentist could have filled a cavity 6 months ago where it would cost me nothing. But let it sit and wait 6 more months so he could put a crown on it. This dentist just wants more money from the insurance company and doesn't care about patient expense.dentist just wanted to be paid money for the free crown he put on cause he didn't do it right the first time and it kept popping off. All this dentist wants is money which is why he dropped hmo plans. I would not recommend this dentist to anyone. read more

My daughter and I have been coming here for a couple of years now. Britney has really taken care of us and really turn our dental health and hygiene around. Thank you for giving us an experience and not just a random check up. read more

I have been coming to Diamond Dental Care for over 15 years. I came to this dentist after a bad experience at another dentist and asked my insurance for a 2nd opinion. Diamond Dental Care works with me to create the best plan for me. They are willing to show me pictures, x-rays, and explain what is going on so we can make the best decision and path forward for me. The staff here I feel actually care about me and my oral health. They are willing to discuss and explain my treatment plan, and together we find the best path forward. Thank you for your commitment to being a partner in my dental care. read more

CARE IS THE FAIR HERE. In A World That is Falling Apart At The Seems Due to It's Failing Practice of Self Centeredness, I Have Finally Found a Dentist Who Not Only Listens To His Patients, But Genuinely Cares and You Can Feel It. It Not Only Reverberates From Him But To His Staff. His Meticulous Attention To His Practice and His Professionalism Also Resonates to His Staff. In Short This Is A Dental Office Working On All Cylinders. They Are All In Symphony Making Beautiful Music. Now, If We Can Just Get The Rest Of The World To Work To Make Others Happy Before THEMSELVES. Thanks So Much Dr.Romi Patel and The Incredible Diamond Dental Staff. I Am In Awe. read more

Dr. Romi is great. They take care of me every step of the way. Staff was very professional

If you're looking to be taken care of come here. The whole clinic was super nice and they took picture to show me what was going on with my teeth!? Never had a experience like this. I've never felt so comfortable that I fell asleep getting a filling, truly Doctor Romi is the best and recruited the best staff I have yet to seen. read more

Britney is outstanding. She made my X-ray experience comfortable, cleaned my teeth gently yet thoroughly, and took the time to explain how to prevent dental damage. To me, she's worth seven stars! read more

Today was my first visit to Diamond Dental Care for the teeth x-rays, cleaning, fluoride treatment and consultation. I was very pleased with an overall experience and impressed by skills of the Dentist and staff. After today's positive experience, I would definitely go back routinely to maintain the healthy teeth. Office is very friendly and spent adequate time to explain the results of teeth cleaning and examination! Office location was convenient near freeway access and minimal waiting time! I would definitely recommend Diamond Dental Care and deserves 5 stars. read more

My wife had emergency gum problem went over to see Dr. Patel. He took one look and said this is not his area and asked her to come back next day where there is specialist on site. She made appointment for 11:30am and was asked to pay $75 fee up front (Why? I have never heard to collect office visit fee before even see doctor) but she did. She went next day, waited for almost one hour, there was another patient before her was waiting too. He couldn't wait any longer and left. My wife had to go back to work so after more than one hour wait later she asked for her $75 back and left. No explanation at all. Even the receptionist was kind of embarrassed. The "specialist" did not even show up. I have no idea all these 5 stars review came from. I was going to switch to this practice and called many times, no one answer the phone. I had tried use online chat to communicate, according to them they will reply "immediately", after question sent and waited for 3 minutes no one came online. I gave up. read more

Amazing service, Dr Romi and his staff prioritize the patient. They make you feel like family and go the extra mile to make the patient feel comfortable. Britney did a great job with my cleaning, best experience i have had at a dental office!! read more

Everyone was super nice and attentive. The hygienist was gentle and did take good care when I got sensitive. I've been coming here for over a year and each visit has been positive. The receptionist is also very welcoming. read more

I had a tooth emergency and I was able to get in immediately first thing in the morning the next day, and I had the best experience from the entire staff. The doctor explained everything thoroughly for me. The doctor also walked me through my procedure and assured me that his recommendations would help me down the line with any other tooth issues that I could potentially have had. The dental assistant Bryana. was amazing, so kind and gentle and Stephanie was able to help me with all my Dental insurance information and kept reassuring me that everything was going to be OK. I will continue to get all my dental care through them and highly recommend and appreciate them so much read more

I've been a patient for 10+ years, but have decided it's time to move on. The change in receptionist from a knowledgeable insurance-savvy woman to the dentist's wife just doesn't cut it for me. The wife is rude, heartless, and clueless. She tried charging $10 to provide me a receipt "copy" that was never given to me in the first place and she has no idea what is needed for FSA reimbursement so simply asks meaningless question upon question. In addition, I noticed that the last claim with Delta Dental charged for X-rays which I never did get. I'm sorry to leave a great dentist and friendly dental staff, but I'm not okay with insurance fraud and people who give me the runaround. Goodbye. read more

Everyone was very nice, there was no wait time, and the dental cleaning was pain free. I have sensitive teeth so I usually have a lot of discomfort during my cleanings but not this time. read more

Dr Patel and Bryana are the best.. always a great experience when I come here for check ups highly recommend this place

Dr. Patel and staff are really wonderful. He is gentle and caring and they all treat you like you are family. I highly recommend them for your Dental needs read more

I would avoid this place at all cost. This is an overdue review as it's been about 3 years since my wife got her teeth cleaned here. They charged so much money on services that my wife didn't even need. Please save yourself time and money and go somewhere else. read more

The worse dentist I have ever paid a fortune to. Last August I paid about $1500 for a crown for my son. His gums have been bothering him ever since then but figured his gums were sensitive anyway. Since he turns 26 soon we had him come back and get a final check up but I had him go to my dentist instead. I stopped seeing Patel when he sold me a bridge and couldn't get it to fit without hurting. I never went back. So my son sees my new dentist and we find out several things- all of which we have pictures of. Patel didn't make the crown fit under the gum line, so food was getting between the crown and the gum. There was massive decay on the remains of the tooth. He also drilled into the next tooth to get the crown to fit. The next step is small claims court to get our money back. When I get photos I'll post them. My wife was seeing Patel though I've encouraged her to switch. Now she will. read more

This is my go-to place for my checkups, and Britney did an amazing job in cleaning my teeth and helping me answer all my questions.

Doctor Romi extremely nice, quick and painless filling, was in and out within the hour. The hygienist helped me numb my tooth and made the appointment very pleasant. I definitely recommend coming! read more

Dr Patel has been my Dentist for a very long time and I am so blessed to have him and his son as my Dentist , the father and son team are amazing and very caring towards their patients. I highly recommend them to everyone in search of a Dentist. read more

Your visit will make you feel like you're right at home. Dr. Patel is expectional and very skilled with educating the patient on his or her treatment. He truly cares about his patient and does a great job following up with them. read more

Diamond Dental Care is simply the best. Coming from a facility of dentists, all of their recommendations, procedures and quotes are spot on! I've been going to Dr Patrl for 18 years now. We travel from Victorville now because we simply can't find anyone better. read more

I actually never even stepped foot in their facility but was beyond impressed with their emergency response service. I called with a tremendous painful infection at 6pm. They made arrangements to see me at 9 am the next morning. They sent me paperwork to fill out so I wouldn't have to do it there. He even gave me advice on how to manage the pain through the night. I didn't end up going because my original dentist called me back and had an opening at 8am. I gave 5 stars because if he was so accommodating to call me back and text me multiple times to make sure it would be a smooth visit then I am sure the visit would have been great too. read more

Doctor Raul Patel is a really good person and I really good dentist, he's not about money is about people ... and I like that ... Thank you read more

DDS Romi Patel, such a nice person. I appreciate you and you whole staff for such a great time. Work done and work plan 100% satisfied. Your teeth are amazing btw! read more

I have no fear going to the dentist because of Dr. Patel and his caring team. From the front office to the wash station where I clean and rinse to be sure I am safe and to keep the dentists and hygenists safe, to sitting in the chair for dental work, I know I am in good and gentle hands. I actually ENJOY going to Diamond Dental. You will as well. read more

The dental team here is awesome! I moved to Diamond Bar in 2017, and two months later, I had an inflamed tooth from food stuck between two teeth. I called up late in the day, and Dr. Patel saw me, pulled the food out and didn't charge me. He just said, come back some time! He is now my regular dentist. His prices are fair, and his team will do everything they can to support your schedule. He also has great relationships with other dentists and oral specialists in the neighborhood - his references have been spot on. I love family practices, especially when you feel like the entire team cares about one another and their clientele. Definitely 5 star! read more

Refused to clean our teeth without full set of X-rays. Reported to Scan and Delta Dental Group. Stay away at all costs. Delta dental provides X-ray cost for you to get you teeth cleaned. Dr. Romi Patel refused us service and wanted to charge additional x Ray charges.. not provided by Deltal Dental HMO plan to just clean your teeth. Bad business in my mind. Beware read more
