    Brittney (sorry if I spelled it wrong) is the scheduler that tries to get me back in the office for…read moretreatment. She's super bubbly and doesn't make you feel pressured to make a decision on the spot. Dental hygienist that worked on me was Angie, very sweet, light hands and if I felt sensitivity she stopped. Saw Dr Kao on 4/29/26 and 4/30/26 for fillings, he was friendly, had great stories and added a lot of humor during treatment. Yvette helped him on both days and they work well together. Yvette always made sure I was comfortable, offered me water and headphones to relax, very sweet and easy to talk to. The office now has cherry payments - like Klarna and affirm which is nice because you no longer have to pay a lump sum. Office is immaculately clean.

    Thank you Dr. Sima, Dr. Kao, and the entire dental staff for taking such great care of me and…read moreeasing my dental anxiety. From my very first phone call with Britney to the warm welcome from Alicia and the whole team, I knew I was in great hands. The office is immaculate, and the state-of-the-art equipment allows everything to be completed in-house, which made the entire experience even more convenient and reassuring. Dr. Sima and Dr. Kao are truly talented dental professionals, and I'm so grateful for the care and compassion everyone showed. Amazing experience! I am definitely recommending all my friends and family to Covina Smile. I am so happy to have found my new dental office!

    Nothing but rave reviews for Total Care Dental. Decent prices (for someone like me who is…read moreuninsured), fast service, friendly staff. Absolute home run dentistry! A few years ago they had a problem with wait times. I used to wait up to 2 hrs to be called in. Not anymore! I was called within 5 mins of my appointment time. Dr. Jennifer Wang is amazing. Very informative and friendly when I asked questions. The rest of the staff is incredibly friendly as well, from the dental assistants to the receptionists to the finance manager. I felt cared for and respected. I would recommend this place to everyone! Will be returning.

    Very disappointing experience at this dentist's office today. My mother and grandparents were not…read moregreeted upon arrival, and the receptionist, Rosa, was unnecessarily rude from the start. When informed of my grandmother's appointment, Rosa demanded paperwork. My grandfather explained it had already been completed online, and her response was dismissive and accusatory. When my mother tried to calmly step in and keep things moving, Rosa interrupted with a hostile tone as if she felt threatened. This level of disrespect--especially toward elderly patients--is unacceptable. The front desk sets the tone for the entire visit, and unfortunately this interaction overshadowed everything else. I hope management takes this seriously and ensures staff are properly trained in basic professionalism and customer service. Sad to see this is the sort of treatment a patient with Dementia gets.
