The office was very clean and welcoming, and they even had toys for her to play with, which helped her feel comfortable and not anxious at all. The doctor was wonderful and took the time to explain to us how to properly brush her teeth and answered all of our questions. Everything was very informative and helpful. The entire staff was incredibly kind, friendly, and professional. We also loved that we didn't have to wait at all! Everything was quick and efficient while still feeling very personal. We're so happy we chose this dental office for our daughter's first visit and would definitely recommend them to other parents!

SHADY BILLING PRACTICES AND ZERO ACCOUNTABILITY: This office…read morequoted us wrong not once, but twice, for different treatments. We agreed to the treatment ONLY based on the price they provided and paid the initial amount as directed. At the second appointment, we were told the price had gone up significantly due to their own mistake and now they expect us to pay for it. That is not how ethical healthcare works. When we disputed the charge, instead of resolving it professionally, we were bombarded with text messages, sent bills by mail, and threatened with collections. I specifically asked to speak with the doctor so she would know how badly her front office is mishandling patient finances. The office manager refused. That alone speaks volumes. Either the doctor is completely disconnected from her staff, or she allows this behavior. Either way, it's concerning--especially for a pediatric dental office where trust matters. I would not recommend this office to any family.

The staff is extremely friendly and genuinely caring -- they knew exactly how to talk to and interact with young children. From the moment we walked in, they made my baby feel completely comfortable. I especially love all the thoughtful little touches they have for the kids. Everything is designed with children in mind, and it really shows. Little Grin turned what could have been a stressful visit into a smooth and positive one for our family. Little Grin is a true gem. If you have young kids (or babies!), this is the place to go. I would recommend them 100% and give them a perfect 10 out of 10. Thank you, Little Grin team, for making dental care such a positive experience!

I took my kid in for cleaning and saw they made him feel comfortable and he was not anxious at all. So when he needed ortho we decided to keep him here. Staff for regular dental services are all nice as well as the doctors and place is kept really clean. The ortho side is just the same, friendly staff and kept clean. We enjoy they decorate for all occasions. This is for Edwin in ortho we were lucky yesterday to get him for my son. He was so patient and explained everything he was doing along the way. He allowed my kid to ask questions and constantly checking if he was ok. It was a longer ortho appointment truly grateful he was the one to help us. He was awesome all around!!!

I have been a loyal client of this practice for over a decade. What initially solidified my…read moreconfidence in them was the exceptional care they provided to my son, who has autism; he began visiting at five years old and is now sixteen. While the practice has evolved over the years, the quality of care has remained consistently high. However, I would like to offer some constructive feedback regarding the administrative experience. It can be frustrating to be repeatedly asked to provide an insurance card that is not in my possession, especially considering our 11-year history with the office. Additionally, I have found the persistent pressure to approve treatments not covered by insurance to be overwhelming. When I decline, the subsequent process--which involves waiting to speak with someone and signing a refusal form--frequently extends what should be a routine visit into a much longer appointment than necessary. I truly value the care my son receives here and hope this feedback helps streamline the administrative process for long-term patients like us

Tina is very compassionate and was so good with my son while prepping. I hope she reads this because I just want to thank her for being so good and gentle with him. Came back today to do the procedure and Dr Shiflett was so amazing with him also. We did the oral sedation this time. She explains everything so thorough and we couldn't be more grateful for her and her assistant Tina who were just so caring. I truly appreciate this office for everything they've done for my son. The front office is also very very nice. Superb customer service.

If you bring your child here, ONLY see Dr. De Guzman. She is compassionate, clear, and made my son…read morefeel completely safe during two years of cleanings and treatments. Unfortunately, Dr. Shiflett completely ruined our experience with this practice. Her attitude is condescending and lacks empathy. Rather than proactively treating my son's tooth or explaining our options, she advised waiting until he was in pain and showing signs of infection just to clear it with insurance. Dr. De Guzman handled a similar issue right away, proving this was completely unnecessary. We will not be returning. It's disappointing to leave Dr. De Guzman, but Dr. Shiflett's dismissive demeanor and poor patient care are unacceptable.

I originally found this dental office just by googling a local dentist. They had really high…read morereviews. Within the first phone call, I already understood why. Dominique was very personable! She answered all my questions. Helped me navigate my son's busy schedule and the dentist available times. She was so patient. She told me Vickie would be calling to help me verify the insurance. Ms. Vickie...is the GOAT. She is so kind!! When you meet her, you feel like she's some how apart of your family?? Or like, a friend you've known a really long time. She so just...kind. Went over every detail of the bill. Made sure I fully understood and agreed with next steps. I appreciated that once in office both Dominique and Ms Vickie spoke directly to my children. Acknowledged them as the patients and as people. The office is very clean. What I appreciated THE MOST, and I told them, was their scheduling was superb. We walked in for a 1 oclock appointment, and was seen at 1 oclock. We didn't sit in the lobby waiting. There was no one in there until we left. We've been there 4 times now (kids needed some cavities filled and we spread it out for time) and each time, no one is coming until we're walking out. They have it DOWN. I appreciate people that respect my time. I hate waiting 30 min to an hour or hour. Arriving on time to sit. The technology in office was very good. The doctor was excellent. Explained everything. Give recommendations. Got the work done. I highly recommend it. And once you meet the front office, you'll know they definitely reflect the back office and the doctor. It's great here.

I will definitely recommend this dental office to my friends and family. I have found my forever dentist!

By the way shout out to Dr Mejia and Amanda the sweet receptionist up front. They were both phenomenal. They even gave me the option to have the filling with crown to be done on the same day but unfortunately we had a prior engagement so could not do it that same day, but nice that they offered that. They were able to fit us in Tuesday, the very next morning. Dr. Ramirez, Lulu and Vanessa were outstanding. They were all so kind to my daughter and making sure she was comfortable. The office manager went over all the paperwork and how much everything would cost. Everything was so efficient. Rooms were so clean and noise level was quiet and calm. I highly recommend this pediatrics dental office for your kids. I rate them a 15/10!!! Best experience!!! Thank you all! And Patty from the office did a follow up call later that day to check up on my daughter and to make sure she was doing well. Now, that is going above and beyond for their patients.

I should have listened to the online reviews about Dental Group of Covina. My experience was marked…read moreby poor communication, scheduling failures, and a lack of attention to important patient care details. My oral surgery consultation was scheduled for 7:30 a.m. on May 20, 2026. I arrived at 7:00 a.m. and found the office closed. An employee did not arrive until 7:23 a.m. and informed me and another waiting patient that the doctors would not arrive until 8:00 a.m. We were told someone was supposed to call and reschedule us, but neither of us received any notification. I later overheard staff discussing how patients had not actually been rescheduled as claimed. The dental assistant and Dr. Kevin Dorsey were both professional, knowledgeable, and thorough. After my consultation, I was given a cost estimate and a referral for a CT scan. I was verbally instructed to fast before the procedure and complete the CT scan. No other instructions were provided. The day before my June 3 procedure, I received a voicemail stating my appointment was canceled because insurance authorization had not been completed. After being on hold for 26 minutes and disconnected, I eventually spoke with the office manager, who suggested I pay out of pocket. When I contacted my insurance company, they informed me that Dental Group of Covina had never submitted the authorization request. My appointment was canceled due to the office's failure to do its job. After filing a complaint, my appointment was reinstated. However, when I arrived on June 3rd, I was told they could not process my CareCredit account and suggested rescheduling again. Then I was asked whether I had stopped taking my medication before sedation. This was the first time anyone mentioned that I needed to discontinue medication a week before surgery. I was never verbally informed, nor was I given written pre-operative instructions. At that point, I decided not to proceed. Too many critical details had been overlooked, and I no longer felt confident in the office's ability to safely manage my care. This experience cost me significant time, multiple trips, countless phone calls, and two weeks of lost pay. Patients deserve better communication, organization, and professionalism than what I experienced at Dental Group of Covina.
