Matthew De La Rionda, DDS

Best dentist I’ve ever been to, and I’ve seen a bunch! Dr. Matt is so friendly and kind and takes his time to explain everything and always makes sure that the patient is comfortable and not in any pain. For years and years I’ve always hated going to the Dentist and afraid of what they will say and do, but at A One Dental I feel comfortable and at ease.
Dr. Matt — his passion for what he does shines through and you just feel like you’ve found a trust worthy good doc :) His office staff and Melody and are so kind and friendly, they work with you as best as they can on payments and what not. If you don’t have dental insurance they have a credit program and I feel have affordable out of pocket options as well. No hidden agenda just kind people and seem to love what they do. I highly recommend Dr. Matt and his practice.

After 2 years of not going to the dentist because of a bad experience with my last dentist. I tried Dr. Matthew and I could not be happier. He took care of my needs explained everything that needed to be done. You could actually tell he cares about his patients. Unlike the last place I went. I would recommend him to everyone I know. Thanks again Dr Matt

I always had a very hard time finding a good, nice, honest dentist who also has great bedside manners and makes you feel comfortable and spends time with you. Dr Matt is all that and more!!! I’m so happy I ended up here.
I have a new born and the first time I got here he even took care of my baby girl while I was getting the x rays done. I love his staff too they are so helpful and friendly. I feel right at home here!
Oh and a plus: he has a GREAT sense of humor!

I have been going here for over 4 years and it has always been a good experience. The staff is very friendly and professional. You never wait long and if you do it is not noticable. They tooth cleaning is as quick and painless as you can ask for. I woulld recommend this place to anyone.

Dr. Matt and his entire staff are AWESOME. I know there is a waiting room, but I have never had to sit there. You come in, are greeted by the nicest and friendliest staff that remembers you by name, and then you are taken to the dental chair. Dr. Matt is kind, gentle with kids, very knowledgeable and overall very personable. He and his staff make the entire dental experience a breeze. My whole family comes here. Tons or parking, clean office, awesome staff, and the best dentist ever.

Upon walking inside the office, I was greeted promptly by a friendly employee. I arrived early for my appointment and sat inside the very clean patient area which had an LCD tv and reading material. I didn’t hear any screaming kids inside, but I did hear some chuckles from a patient who seemed to have had a pleasant appointment. Prior to march 31, I hadn’t seen a dentist in over 6 years so all these signs seemed like great news.
Moving along, Dr. Matt later looked at my x-​rays and explained the procedure I would have (basic cleaning and then a filling for a large cavity I had). I told him my fear of going to a dentist even just for cleanings and he made me feel at ease the entire time. During the appointment, he didn’t talk to me while my mouth was open and couldn’t respond like the dentists I’ve had before. Occasionally he would pause, make sure I was comfortable and told me to raise my hand if it wasn’t. He has a very calming, professional voice and seems like a patient person.
I highly recommend dr. Matt for anyone who is afraid of going to dentists. He really makes you feel at ease and explains everything very well. I would also recommend him for parents looking to take their children in as well. His calming personality would make them feel comfortable.

I recently left my dental office of over 30 years after they sold to a new group that was dreadful. Dr. Matt had great ratings, both here and elsewhere, so I gave him a try. So glad I did!
I am terrified of dental work. TERRIFIED. But Dr. Matt and his staff put me at ease. Everyone is friendly, and Dr. Matt works quickly and efficiently, explaining everything he does and checking in often. Even his shot of anesthetic barely stung.
Happy to recommend him, Melody and Karina!

GREAT DENTIST!!!
I was lucky enough to find Dr. Matt from the Blue Shield website about 2 years ago. I had been neglecting my dental care for many years and wanted to find a new one to start my overdue dental treatments. I lucked out with him and his new practice. It is very convenient with lots of free, easy parking and in a great neighborhood with lots of nice restaurants, coffee houses, shops etc.
The office is very nice, modern and pleasant with what seems to be all the latest equipment. The staff are very friendly, easy-​going and accommodating with insurance as well as squeezing you in for an emergency or last minute appointment. Dr. Matt is a great guy and Dentist. He is patient, informative, gentle, relaxed and doesn’t suggest any unnecessary procedures.
I have recommended him to many people and would recommend him to anyone reading this. You will be very happy with he and his awesome practice. My only fear is that he’s going to become so popular and busy that I won’t be able to get an appointment.

Great place to go, Great Staff and Great Dentist. Really nice place and the staff is super nice. I would recommend this place to anyone.

I went with a voucher as an intro for a new dentist. I was hoping for a better experience than the last time I went to a new dentist last year.
I parked in the ample parking lot and went to find the office. Hint — they are on the top floor kind of in the right hand corner at the back if you are standing face on to the complex.
Score one was they were actually open when I arrived! No waiting an hour like the last place! Also, the patient leaving was either Kiwi or English so I knew that was a good sign — well for me!
Filled out the regular paperwork, was taken in immediately for x-​rays — the nice kind where you see them digitally on the screen in front of you. The tech/​hygienist was very good at this especially since I seem to have developed a sensitive gag reflex.
Dr de la Rionda was great. He checked everything out and told me everything was fine and he recommended a check up and cleaning in 6 months. Great news, the kind I like to hear!
He then cleaned my teeth! He, the dentist! Whatever he used was AMAZING! My teeth have never felt cleaner and it involved no scrapping whatsoever. It was like a sonic thing… I did ask but can’t remember. It was painless but noisy as hell. Still the results were worth it. He even managed to get rid of the residual braces glue on a tooth from over 15 years ago!
Nice location and friendly, helpful staff.
See you in six months Dr de la Rionda !

A native English speaker, this guy is awesome. He’s very approachable, non-​pretentious, and makes no attempt at trying to upsell you on costly procedures. I felt very comfortable when he was all up in my grill singing that 3−2−3 jam.

Dr. Matt and his team (Corina & Melody) are the very best dentist and dental office I’ve ever attended.
Dr. Matt and his staff are extremely courteous and professional. Sufficient time and care was taken to take x-​rays, perform the cleaning and thoroughly review my overall dental health situation. I felt very confident with the selection of Dr. Matt as both my general and cosmetic dentist.
I am pain sensitive. Extra care was taken so that I felt no discomfort. Each appointment experience «flowed» very well. There was no feeling that I was hurried, or the work was rushed in any way or any shortcuts were taken.
Dr. Matt is meticulous with all of his work. With regards to my cosmetic veneers– I now have the smile of a lifetime-​It looks very natural and I am receiving unsolicited positive comments. I am still pinching myself and finally smiling «wide and open».
I am extremely happy and more than satisfied with both the dental experiences and the results. Truly, no one could have done better.

For my money I want the best. I look past a well appointed office, friendly staff and an unintimidating professional. Dr. de la Rionda not only did not disappoint but was actually impressive.
He was trained by California’s very best. He possesses ‘pearls’ not found in text books. That is why he is different from your average dentist. He takes a history, reviews your medical history, collects the data, explains the differential diagnosis and then the diagnosis and the treament plan. All so impeccably and thoroughly performed. Then the moment of truth. His technique, effciency and the lack of discomfort was truly remarkable. Recovery was as he predicted and so thankfully uneventful.
I wanted to bring him to your attention because I have been to incompetent ones, needle reusing ones, money grubbing ones and the worst of the lot, dishonest ones. This is one office the community should be proud of, support and help grow. Otherwise we will find ourselves surrounded by the not so desirable ones.
Start here if you:
need a new dentist.
have a dental emergency
have some one quoting you thousands of dollars
have questions about your current dentist
worried about out living your dentist’s career
treasure the tangible and intangible qualities in a professional
want to get things right the first time and value for your money
Dr. de la Rionda is simply superior and the best in the Valley. I give him the highest recommend without any reservations.

I had a very great experience here. The staff is very nice, the equipment is very up to date, and the dentist is extremely friendly and knows his stuff. Definitely one of my better dentist experiences.

The staff is amazing. I was able to get an emergency appointment right away. Dr. Matt is a sweetheart and a very good dentist. They hooked it up. I’m so glad I found them!

Friendly Dentist & Staff… SCORE!
Came here via the god Awful Anthem Blue Website.
I was able to book a spontaneous appointment with no trouble.
Ester, the receptionist was cordial, down to earth yet professional. She help me sort out insurance mumbo jumbo.
The X-​Ray Girl was incredibly friendly.
Dr. Matt was very professional as well. He gave pretty black & white explanation of the work to be preformed.
The Hours of operation are very convenient as well.
They allow appointments as late a 5pm, which is great for those who work the 9 – 5
Just off Ventura Blvd, the 101 and near the 405.
I would refer someone here for sure.

When I think about the dentist, a flashing red sign saying, «DANGER!!!» is all that comes to mind. I’ve never been a fan of any dentist because I never left a dental office feeling good about my experience. In fact, I would wait long periods of time before I went to another appointment, which never turned out in my favor because I’ve always had dental issues since I was a child. Avoiding your regular treatments is a definite «no no», but when you have as much anxiety about the dentist that I have… it’s the only way to go about the situation.
After not going to the dentist for several years, I was recommended by a friend to go to A-​One Dental and see Dr. Matt. My friend raved about him and his staff… speaking of her great experience from beginning to end. That sounded like a lie, but I knew I had to go in and get a lot of work done, so I sucked it up and made an appointment.
When you enter A-​One Dental it feels like you are entering a spa. The waiting area is so nicely decorated and has a wonderful serene feel to it. It’s not your typical stuffy office feel. The lady at the front desk was also very welcoming. I checked in, filled out some paper work, and had a seat. At that point I was very pleased.
A few minutes roll by, and another lady came out to greet me. She was also very nice. I followed her in, and immediately got nervous. That anxiety started to kick in. DANGER! DANGER! Ahhh!!! I tried to calm myself down. I didn’t want to seem like a complete wuss. I took a seat, and Dr. Matt came by and introduced himself. He noticed that I was a bit nervous, and reassured me that everything would be okay. He took a couple of x-​rays, which was followed by a painless cleaning. That was a definitely a plus. Afterwards, we went over my treatment plan, and he reassured me again that everything would be okay… and for the first time in my dental history… I actually believed what a dentist was telling me. I even scheduled my next appointment before leaving. That’s definitely a first for me. =)
The problem I’ve with past dentist are the fact that they make me feel so bad about not taking care of my teeth. I know that I have issues, but I also have anxiety about going to the dentist for good reason. Every single experience I have had prior to meeting Dr. Matt have been a terribly painful ones. I’m happy to report that A-​One Dental is my new dentist. The staff is wonderful, the place is super clean, and there are tons of parking space. I highly recommend Dr. Matt to anyone who wants to walk out of the dentist feeling good about their experience.
