If anyone chose to go there, I wish you a good luck! I would NOT recommend anyone to go there! We had a really BAD experience and got trapped. 1. The treatment was processed without my signature on consent of the treatment plan, which was considered as assault. 2. Violation of HIPAA rule - The dentist leaked other patients' confidential information. - Date of Birth, treatment information and statements. The front desk sent me other 3 patients’s statements. 3. Mercer Island Pediatric Dentistry misled and misinformed clients on the treatment cost. The Dentist failed to disclose all the costs. She didn’t make sure patients clearly understand the procedures she is performing and the costs associated with those services. I was not clearly informed of the financial responsibility for services. The dentist failed to offer coordinate insurance benefits, follow through. Some details on our bad experience: Don't trust whatever the front desk manager and the dentist tell you on the cost estimate, because they will only give you some misleading on your payment portion. First, they will say insurance covers most of it, then after treatment, they would let you pay in FULL(100% of the bill). That's a huge difference -- adjustment or pay 100%, it's not called an estimate, it's called assault! That's what happened to us. If your child goes there for teeth cleaning and treatment, please call your insurance company by yourself to verify everything they will do BEFORE your treatment, don't trust the front desk manager, she will NOT check with your insurance company. You are the one who sign and pay, she only asks for checks, not caring about clients! We ended up with paying 100% of the bill out of pocket! We have dental insurance and I don't know what happened between the dentist and insurance company's relationship. We just want to get rid of them, and move on. After we paid off the balance, the front desk didn't even send a receipt until I called in and make sure they process it and sent over to me. Otherwise, they just skipped it. People CANNOT trust them, not recommending anyone to take the risk! * Check the Yelp reviews for more references. Some other clients also had bad experience.
