I have been coming to this dentist for years. Dr Armienta is the best dentist in whittier and i’m being serious. He is very gentle with teeth. Never felt any pain. I highly recommend coming to him. His staff is amazing too. Everyone at this dentist is friendly and caring. From the lady at the front desk to the two wonderful ladies helping armienta, their all so nice. I couldn’t ask for a better dentist tbh. The only thing though i recommend sticking to the minty tooth paste, the berry flavors are not the best

DR. ARMIENTA IS THE BEST. I was sent to him because other dentists messed up and did work they shouldn’t have. Dr. Armienta is there most thorough and conscientious Dentist I’ve ever been to. He uses the best materials. Be aware just like there are good and bad mechanics, there are good dentists and bad dentist.

Amazing office! Patient, caring staff and a lot of fun! I’ve been going with my 3 kids since they were very little, for over 10 years now and they love their Dentist. I highly recommend them! Go in for a cleaning and you will see

Dr Armienta has been our family dentist for many years.  Whenever anyone asks, I always say my dentist, Dr Armienta, is the best dentist in the world.  I needed a root canal done and had heard it was very painful.  I was not thrilled that I needed one, but scheduled my appointment.  The first of two appointments was pain free; as I scheduled the 2nd appointment I asked if the next visit was the painful procedure that everyone complains about.  I was told that I had just finished with the major work; the next appointment would be a breeze.  Wow, what a relief.  I worried for nothing.  A root canal was no big deal.  In fact, I have never had a difficult or painful experience with Dr Armienta, the best dentist in the whole world

Ruben and his staff are by far the best staff I have ever met! I have been going to Ruben my whole life and I am 17! He is the only dentist I have ever had an I can definitely say my family and I are always taken care of by Ruben and his amazing staff!

I’ve been going to Designing smiles for over 10 years. I have never had any issues. You never have to wait in the lobby for your turn, appointments are always available, always friendly and welcoming and Dr. Armienta does his very best to have a painful experience

Arlene L. from Whittier, CA (Source: Yelp)


My husband and I have been going here since we married over 13 years and we are very pleased with the services and professionalism. We are seen quickly and feel valued as clients. We get answers to our questions and through explanations. If you are looking for a dentist, look no further!

Lorraine F. from Whittier, CA (Source: Yelp)


I highly recommend Ruben Armienta. I’ve never had a bad experience at Design Smiles by Laser. I always walk out of his office knowing I received top quality work. The staff are always friendly and helpful. You’re in good hands with Dr. Armienta!  He is trustworthy; he will not do any unnecessary work. He also has a good heart! He has donated a great deal of toothbrushes to children and families in Cambodia 🙂 Don’t go anywhere else but here

Erik T. from Buena Park, CA (Source: Yelp)


I’ve been going to Dr. Armienta since I was a teenager and now my wife goes too. Great practice, feels like family. The doctor is thorough, patient and always a great conversation. Hope our baby gets to come here too!

Kristina S. from Downey, CA (Source: Yelp)


I have been going to Dr. Armienta since The 90’s. I’ve never liked getting dental work done (still don’t) but thanks to Dr. Armienta and his friendly staff my pearly whites are in great shape and I feel at ease every time I visit. His staff is great at sending check up notices and appointment reminders. I have continued to see Dr. Armienta even when I lived in Northern California, and there is no other dentist I would even consider

Debbie P. from Whittier, CA (Source: Yelp)


I came into the Dennis office very nervous and scared they’ve made me feel very comfortable and  relaxed recommended this dentist explained everything to me.

P. T. from Whittier, CA (Source:Yelp)


I’m terrified of dentists and only showed up in this office recommended by 1-800-Dentist to get a crown re-cemented.  I felt so comfortable with Dr. Armienta and the staff is especially awesome. I had the crown replaced as well as four others.  I’ve never had such a beautiful smile! Dr. Armienta will be my family dentist as long as he is practicing.  I no longer fear going to the dentist.  Nothing he did hurt me and I never saw ANY dental tools.  This dentist and his office is top notch and I would recommend him to anyone any time!

Jaime S. from Los Angeles, CA (Source: Yelp)


My two children now are young adult have been going with Dr Armenta for almost 30 years… we are very happy with him and his staff very polite very courteous

Claudia M. from Whittier, CA (Source: Yelp)


We came here for the first time under some stress because my 7 year old had a bad toothache and my insurance is new, and i was not sure what the insurance provider was. The front office staff, Letty, was so helpful and patiently helped determine the insurance and squeezed us in for a last minute appointment.  We got some bad news about my son’s teeth.  He had 8 cavities and a gum infection/absess!  I was in a bit of shock to wrap my head around this, but the dentist and his staff helped explain the problems and swiftly, on a Friday afternoon, took care of the problems.  My son’s teeth quickly healed and the asess was removed.  We all learned the hard way (especially for my son) that we need to take better care of our teeth and brush 4x a day(!) and floss regularly as well.   On his day off, the dentist called home to check on my son’s healing from the procedures!!! I am so grateful to the staff for their patience and kindness during a stressful time.  My son was crying much of the time due to the pressure and pain, and they were reassuring the whole time.  2 days later and he is back to his happy, playful self.  Thank you ALL so much, you are very professional and kind

I have been a patient of Dr. Armienta for over 10 years.  You will not find a more caring dentist and office staff.  They have always treated our family with great care

Melissa R. from Fullerton, CA (Source: Yelp)


The staff here are super wonderful!! They are welcoming and always ask how I am doing as well as my husband and daughter. They genuinely care about my wellbeing. I have coming here for about 5 years now even though I live in the OC I make the trip to Whittier because I love how clean and welcoming this place is! It is in a converted house so it still has that warm and cozy feel. The waiting is small but has comfortable. They have a good magazines and a small tv to keep you busy even though the wait is not long. Every exam room has its own tv as well. I was referred here by a friend and thank her every time because I have found the best dentist with amazing staff. They are really gentle and careful to take care of me sensitive teeth. I have referred my friends and co-workers here too. My husband comes here now too and he loves it! It is a small place and does get busy so make sure you make your appointment! And tell them I referred you!

I brought my son to Dr. Armienta’s wonderful dental office. the receptionist was very kind and the waiting area (lobby) made us feel at home – because it actually is a home that’s been modeled into a dental office with the latest dental equipment technology. My son said everything went smoothly and not one tear in his eye. I’m next. Hi Ashley Eubank! Please give Dr. Armienta a try, you’ll leave with a smile.

Diane V. from La Puente, CA (Source: Yelp)


I hadn’t been to the dentist in over 5 years and was very hesitant about finding a new dentist. I found Dr. Armienta on Yelp and was very hopeful this would be a good idea – and I was right. Not only was the Dr very nice, he also explained everything he saw on my xrays and his recommendations. He was not one to beat around the bush and I appreciated that. The staff is great! Letty explained what my benefits covered and assured me I could use my FSA to cover my portion of the costs. Maria and Stella were both kind and patient when I needed a moment to get it together. They were reassuring and made me feel comfortable even in what was for me a very uncomfortable situation. I got a much needed deep cleaning my first appointment and two fills (one to save an otherwise root canal) on my second visit. It was a great decision to come here. They’re a small office, but the quality of the staff and the work done is anything but small

Helen D. from Whittier, CA (Source: Yelp)


Amazing office! Dr. Armienta is amazing, his team is awesome! They are all so patient and caring. When you go there you feel like family. I’ve been going with my kids for over 10 years, since my kids were little and they love their Dentist!

Tyler S. from Laguna Hills, CA (Source: Yelp)


I really like it here. The waiting room feels homey and comfortable. The staff is really nice and professional. Dr. Armienta runs a clean and good practice and he knows what he’s doing. I definitely recommend this practice to anyone looking for a dentist

Joe F. from South Pasadena, CA (Source: Yelp)


I have been a patient for 21 years. He and his staff are personable and friendly. He has never suggested anything that is unnecessary. All concerns are taken seriously. I will continue to be a patient

Denise G. from Whittier, CA (Source: Yelp)


The staff is outgoing and friendly. They sure helped put me at ease as I always get nervous coming to the dentist. Dr. Armienta was the first dentist ever to tell me that I have TMJ. He explained the dangers of opening my mouth too wide and was able to work with me during my deep cleaning. After struggling so much with other dentists to open wide it was a relief to finally find a dentist that was so accommodating. He also didn’t scold me for not flossing as often like all my past dentists. Very kind and comforting. I’m eternally grateful; I’m definitely recommending him to everyone I know

Nettie A. from Buena Park, CA (Source: Yelp)


Been going to him for years!  Best dentist and friendly staff! My husband and I live in Fullerton and we still travel to Whittier for his dental work!

E. I. from Glendale, Los Angeles, CA (Source: Yelp)


Have been going to this place for about 3 years now and the staff is so friendly! We switched from another dentist in diamond-bar because he decided he was going to do a crappy job in pulling out teeth and cleanings. We were recommended to Dr. Armienta by some friends who were family and decided we had nothing to lose. It all started with a simple tooth removal that I did not feel at all compared to the other unexperienced dentist , and he became our permanent dentist. He is very professional and the staff is very polite and respectful. They are also very quick and still end up giving you a good cleaning. The waiting room is always clean and packed with magazines to read while waiting.  Like I’ve seen on a previous tip, don’t try to say you floss every day, because he knows lol. Thanks Dr. Armienta! 🙂

Charlene M. from Norwalk, CA (Source: Yelp)


I have been coming to Dr Armienta for over 5-6 years now…maybe even longer. I found him through 1-800-DENTIST (I think) and he was right down the street from where I lived in Uptown Whittier. The office is converted from a house and has a waiting room, 3-4 exam rooms, a front desk and an office for Dr Armienta, somewhere in the space. Everything is clean, decorated warm and inviting, lots of up-to-date magazines and a tv. The only time I’ve really had to wait there was when my husband was in back and I was watching the kid or for a very short time between clients. Usually, I’m taken back pretty quick and his dental assistants do the laser imaging of my teeth while he’s finishing up with the client ahead of me. I usually lose track of time, because there are flat screens in each exam room and they always give me the remote so I can watch whatever I want. I love tv and that’s a selling point in my book. Anyway. Dr Armienta and all his staff are very personable and professional. He tells you the truth on what you need and let’s you know what can be put off for another time. He really works with you. I have recommended Dr Armienta to several people and they have gone and they are fans and their spouses are also now clients of his. He’s great. Dentist visits are not fun, but I do enjoy my visit to this office. You might, too

Dr. Armienta is an artist!!  He is very knowable, thorough, sensitive and painless.  He runs a wonderful office with a competent and friendly staff.  Love this guy!!

Diana C. from La Habra Heights, CA (Source: Yelp)


Dr.  Armienta is a wonderful dentist.  He takes great care to make even the most complicated proceedures painless.  He is a perfectionist in his craft and is a highly skilled practitioner.  The office runs well (appointments are always on time) and if you need to get in to see him the staff will go out of their way to accommodate you.  Dr. Armienta’s assistants are delightful and also top notch professionals.  I highly recommend this dentist.

Jess T. from Whittier, CA (Source: Yelp)


My entire family comes here . Very clean, TV in every room and very friendly staff! Wasn’t a big fan of the dentist until I started coming here. Thank you Dr. Armienta!

Letty C. from Whittier, CA (Source: Yelp)


Just came out of my dental appointment and as always it was a pleasant visit. The dr and his staff as always are  AMAZING !!!!From the moment you walk in you feel as if you are family. It’s cozy and feels very homie. You don’t get the huge scary dental vibe there. Great selection of magazines to choose from and he even has cable in the rooms to watch tv while we wait… Which by the way the wait time is never long. He explains every procedure in detail so I never feel overwhelmed by anything getting done.  Love my dentist and if anyone is looking for a great one I highly recommend him. I was informed by Dr. Armienta staff that yelp thinks my post is fake and are not allowing my review to show in his page only because my name is the same as the receptionist. Yelp their are a lot of Letty out in this world. Please post my review in my Dr. Page to show people what a wonder Dr he his along with his staff!!!

Patricia C. from Whittier, CA (Source: Yelp)


The absolute best dental practice EVER!  Dr. Armienta is a great dentist and he is kind, patient and always looking for new ways to mitigate pain.  The staff is wonderful, friendly and professional.   I could not ask for a better dental practice

Susan D. from Whittier, CA (Source: Yelp)


From start to finish I was pleased with their friendliness, professionalism, and patience. The whole team took extra time to make sure I understood my treatment plans and options. It sounds cliché, but it’s true: I feel like they truly care about me as a patient. I was not just a $ sign to them. Thank you, Dr. Armienta and team!
