EXCELLENT Based on 106 reviews Posted on Saleha TahirTrustindex verifies that the original source of the review is Google. One of the most crucial things for me when deciding on a care provider-besides communication-are good manners. I'm sure all of us can relate that when we feel vulnerable we look for empathy, kindness & our humanity restored to us; not as another number on a checklist but an actual human. I've found that to be the case here with Dr. Costello & his wife, Dr. Ngo. They are kind, wonderful, will ensure you're comfortable throughout your consultations & exams. They communicate very directly & thoroughly which is a skill I hope they maintain forever. On top of that, they have hired staff which are equally kind & sweet. This seems to be on the forefront of their establishment. Dr. Costello has the most gentle yet firm hands. My experience with him was seamless. He's funny too! Great work, great character. 1 recommend looking into them if you're considering a dental visit! You wont regret it.Posted on Margaret OttoTrustindex verifies that the original source of the review is Google. Truly this was the best decision to go there. Everyone was so kind, professional and so helpful. The entire office is spotless. The dentist’s bedside manner was impressive. She explained everything that I needed to know. Great experience all around. Highly recommended this dental practice.Posted on jennifer rombergerTrustindex verifies that the original source of the review is Google. Ive been with this practice for years. Could walk there and first time I was overdue for my six month checkup. Ugh a cavity...maybe partly due to chemo...was battling cancer at the time. Years later Ive now had root canal and crown. Both doctors and their entire staff are warm, explain things clearly, and extremely caring and cordial. I recommend them 100%!!Posted on ShellyTrustindex verifies that the original source of the review is Google. I have been going to Dentists on Washington for 5 years now.

Outstanding Rick CPosted on EGWTrustindex verifies that the original source of the review is Google. I had a great experience with the team at Dentists on Washington. They were able to squeeze me in for an emergency visit on a Saturday, and find time in their schedules to get all of my needed work done in the same day. I struggle with anxiety at the dentist and everyone on the team was reassuring and kind. Dr. Ngo was kind, professional, patient, and did a wonderful job. I would recommend this business to anyone who struggles with dental anxiety.
