    E I.

    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! :) A.I.

    Letty explained what my benefits covered and assured me I could use my FSA to cover my portion of the costs.

    Dr Yoon is TOP NOTCH. Extremely Efficient, knowledgeable…read moreand very Caring. With my last dentist I was just a number and received mediocre work for my dental issues. They made me dread having to go to the dentist. However, this is NOT the case with Dr. Yoon, she makes you feel comfortable, explaining everything throughly. I highly recommend Dr Yoon, if I could leave a 10-star rating I would.

    I'll admit, I have a great of anxiety when it comes to visiting the dentist. Even thinking of the…read moreword, "dentist" makes me feel as though I bit into a lemon. I recently had such a bad toothache that the right side of my face was going numb, I was sleeping less than one hour per night and I could not drink ANYTHING for over five days. I was in denial, avoided visiting the dentist and took Tylenol so often as though I was eating M & M's thinking the pain would somehow go away. With that in mind, I put on my, "big boy pants" and visited my dentist to find out what the heck was going on with my tooth. Upon my arrival, i was welcomed back by the entire staff with warm smiles and greetings. The staff here are truly friendly, welcoming and professional. In less than three minutes of my arrival, I was lying on a dental chair awaiting the Dr. Yoon, my dentist. Dr. Yoon has this way of calming me down and getting me to relax immediately as she knows that my anxiety level is always high as soon as I step foot into her office. This visit was no different. Dr. Yoon examined me, had X-rays taken and immediately discovered an issue which would require the dreaded root canal. Due to my time schedule limitations, I made an appointment for a few days later and returned. At my next dental appointment, Dr. Yoon discovered that I had a fractured nerve and that this was causing a great deal of inflammation and was the source of my pain and numbness. Dr Yoon and her staff immediately got to work and in less than two hours, It was all done. The pain, numbness and my anxiety were gone. Wow! It felt GREAT to be painless once again. I have to return in two weeks for a permanent crown on the repaired tooth but the anxiety is no longer there and I am actually looking forward to visiting the best dentist and staff in the world. Thank you for the AMAZING service and care to everyone at Whittier Family Dental. I TRULY appreciate you all.

The…read moredentist has always been a touchy topic for me, but I feel so lucky that I can get care at a place that is invested in me. Dr. Cody is funny, gentle and kind. He has got the best personality and I look forward to all my appointments with him. He provides great care and does it so personably. Dr. Barry is knowledgeable and performed a difficult root canal that went quickly and smoothly. Alyssa, my hygienist is so sweet and when she performs my cleaning has the delicate touch needed while doing a thorough job. Office manager Liz is always helpful and I look forward to catching up with her when I check-in. I highly recommend coming to this location. I've been a patient of modern dentistry for over 10 years and when this location opened closer to home I was nervous I wouldn't like it. I'm so glad I do and as long as this staff is still there I will continue to be a loyal patient. Also note parking can be tough at later times because it is a busy shopping center. Facility itself is a brand new build, rooms have always been clean and I've always felt safe under their care. Highly recommend the gum laser treatment! My dental health has improved since coming to this location.

    Really disappointed because I had been here before without issues, which is why I came back…read more When I checked in, they asked if my insurance was still the same, and I confirmed I still have Delta Dental through my employer (I've been with my employer for 3 years). Based on that conversation and my prior visits, I had no reason to think there would be a problem. Later, I found out I was assigned to an out-of-network provider, even though there were in-network providers in the office. That was never clearly explained to me beforehand. They also did imaging that my insurance only covers at certain intervals, and no one told me beforehand that it likely wouldn't be covered. I ended up paying $872 out of pocket, which I did not expect. If I had known any of this up front, I would've made different decisions. Just frustrating overall because I returned based on prior good experiences and left feeling blindsided by the cost and lack of communication. I'd recommend people double-check exactly who they're seeing and what procedures are covered before agreeing to anything.
