Dr. Ali and his staff are the best. I had a horrible pain and horrible experience with other dentists and needed root canal so I called the office and they were able to take me in the same day!!! I was very nervous and my gum was all swollen and in pain but Dr. Ali and his assistant Cecilia was so gentle and so sweet and caring that I was able to relax and forget about the pain. Even the needle poke, I was afraid that I’m going to feel tons of pain when Dr. is going to poke my gum, however I didn’t feel a thing!!! I can’t say enough how great it was, if you want painless root canal and comforting staff you should def go there, they use nice cover that prevents water, medicine and little pieces from getting inside the throat, also they make it amazingly nice so you can breath easily and relax your jaw almost every 30 seconds or so, I was super happy about that because other dentists want you to keep you mouth constantly open that gives me huge headache.

They are awesome. Their entire staff has outstanding customer service and the doctor is very understanding of people who have a fear of the dentist. There was no pain during my entire procedure ‘root canal’ and the staff talked me through the whole thing. I was very impressed and felt very comfortable in the hands of the staff.

Wish I could give Dr. Ali and his staff 10 stars! Due to bad dental experiences over the years… I have not taken the best care of my teeth… and having to pay the price now. I was referred to Dr. Ali from my new dentist for a root canal consult… having the fear that I do, I was not looking forward to the visit. As soon as I walked in the door, I felt at ease from the greeting I received. Headed back to the chair… with my heart pounding… I was greeted by the Dr’s assistant… I wish I could remember her name… she was awesome. Dr. Ali walked in and we chatted for a bit and at no time did I feel pressure to do anything. I felt so comfortable with him I said. lets do this and within 20 – 25 minutes my root canal was done! During the process his assistant told me everything that they would be doing. I felt no pain and was so at ease… had no anxiety at all!
Thanks you Dr. Ali… I strongly urge anyone who needs to have dental work done to see Dr. Sami Ali!!! He is awesome!

I was more then pleased with my experience here. Dr. Sami Ali and his staff are exceptional! Dental work is scary to begin with, but I felt completely at ease and pain free. I would definitely refer this office to ANYONE needing dental work. I’m so glad I was referred here. Office is clean and organized, the assistant explained everything the doctor/​dentist was doing before treatment and while he was doing it. First pain free dental work I’ve ever had done. Thank you so much to the entire office.

When my regular dentist started my root canal, then stopped and told me that my roots are twisted and that I’d need to see an Endodontist, I kind of freaked. I had a severe case of dental anxiety, and once I found my dentist, he was finally able to alleviate it. So imagine my concern when I heard that I’d need to see someone else.
I actually found Dr. Alli by perusing Unilocal and reading reviews. The reviews are amazing so I thought I’d give him a shot. I am so happy that I did. The office is nice and clean, the staff is very friendly and informative, and Dr. Alli himself is a god-​send. He was very nice, very accommodating, and also very informative. He was so gentle, I barely even felt the shot to numb my mouth. The entire time the procedure was taking place, the assistant filled me in on what was happening.
This was an amazing experience. And I would say, to anyone who gets to the point of needing a root canal, this is where you want to go. I would give this office 10 stars if I could!

OMG loved this place. My root canal took 30 minutes and the doctor was so patient in making sure I was fully numbed, comfortable and informed on what procedure he would be performing. Literally one of the best dental experiences that I have had in my life. Thank you so much!!!

You will not regret this choice, I needed help and fast. My dentist highly recommended RC Endo and the ultra professional and sweet Dr. Ali. He was right, they got me in the same day and it was painless, of course I’m a little sore now the day after but that’s to be expected.
I’ve had other root canals so yes, I can judge. The office people are so sweet and helpful. If I need another root canal I would not hesitate but run to Dr. Ali. Love him

Awesome Endodontist! Really, who wants to have a root canal? I’m not happy to have needed one, but I am so glad I came to Dr. Alli to have it treated.
He was very kind and took the time to answer ALL my questions before the procedure. He was thorough and made sure to ask if I was comfortable along the way.
The office is clean, staff was friendly, and they double checked my insurance payment.
The icing on the cake and reason for 5 star review? I had some pain in the capped tooth (2 years after the root canal). I called their office, they got me in quickly, and Dr. Alli did a xray and exam. Found out the tooth was free from infection and pain was due to teeth grinding. What a relief and even more, Dr. Alli provided the re check at no cost. My general dentist (who no longer takes my insurance) refused to even talk to me over the phone!
Dr. Alli, I salute you!

They are amazing! The staff is extra professional and courteous. The office has state of the art equipment. Dr. Ali was honest and helped me pick a realistic and reliable outcome. The best endodontist office I have ever been to. They also have after hours services available for their patients. I can’t thank them enough for their help and care. Will recommend my family and friends to RC Endodontics only! Their Long Beach office was closed so they were able to squeeze me in to the Rancho office and I am very grateful for this and willing to make the drive considering the urgency of my situation. Thank you to Dr. Ali and his staff!

Dr. Ali and his Staff are wonderful. No words can say how good he is. I felt absolutely no pain. From the shot to the treatment. Him and his staff are so professional and explained everything that was going on. I never knew getting a root canal could be a pleasant experience. But i was so relaxed with them. From the time I signed in to the time my treatment was done was only about an hour. he is worth every mile you have to drive and every penny you pay. Will definitely be referring people to him! Thanks Dr. Ali & Staff!

I needed an emergency root canal that my regular dentist was unable to do on a Friday afternoon. Dr. Sami Ali and his staff told me to come in ASAP! I was in a lot of pain! They took care of me and spent quality time explaining what was happening at all times. I have never been here before! All as I can say is they did a GREAT JOB! Very professional! Thanks for taking me at the last minute when nobody else could! I will NEVER forget what you did! Anybody would be fortunate to be a patient at this office. Thanks Dr. Sami Ali and staff!

I was a little nervous going in for my root canal as many people have told me how unpleasant it can be. Yet Dr. Ali made my root canal a painless one. He is an easy-​going gentleman; which made me feel comfortable and less worried about the procedure. He and his assistant were very attentive throughout the procedure. They kept telling me what they were doing and if I was ok.
They have a nice facility with clerical staff that are very knowledgeable and gave me all of the info that I was looking for when I asked questions. They even followed up with me a few days after the procedure to make sure that I was pain-​free.
I highly recommend Dr. Ali and his staff to anyone in need of a root canal.

I walked into the office and not only did the place look very nice and well taken care of, the staff was friendly and genuine. The assistant was gentle and wanted to ensure I was not in any discomfort during the X-rays…those hard plastic things hurt! Dr. Sami Ali came in and introduced himself… shook my hand. He was professional, did a thorough check on the tooth I was referred for. He explained everything he was doing and asked pertinent questions. Although he gave me great news about not needing a root canal, I was able to engage him in discussion about his degrees. He took the time to speak to me and give some advisement. He is also a professor at USC. Sorry people, but you can’t be more credible and awesome as this man!
Dr. Sami Ali… good old fashioned care… he makes you feel comfortable, takes pride in what he does, and is genuine. People like this are hard to come by these days. I love it and wished there were more like him.
