"Dr. Thu is great however the Belleville office is the most dysfunctional I have ever dealt with. Rarely does anyone answer calls. You are unable to leave a voicemail. If you do get someone on the phone be prepared to be transferred to someone who knows less than the last one. I have been waiting for response since early May and office does not call back. I feel they are negligent in providing Dr. Tsu with timely and critical patient information that would allow him to treat patient as needed. Completely unacceptable. "

Data Transparency and Trust: Understanding WebMD Doctor Listings and Reviews

We know that finding the right doctor or provider is important to your health. That’s why we want to ensure you have confidence in the provider profiles and listings you see on WebMD Care. Our provider data is sourced from the physicians themselves as well as publicly available databases. Any doctor or provider who claims their profile by verifying themselves can update their information and provide additional data on their specialties, education, accepted insurances, conditions they treat, and procedures they perform.

All the physician and provider reviews on WebMD Care are provided by users just like you. Knowing these reviews provide insight into how other patients feel about a doctor, we maintain internal policies and protocols to ensure the quality and accuracy of all reviews. Providers are not able to remove or modify reviews on their own. Reviews can only be removed after an internal review by our customer service team.

We value your input and encourage you to reach out to our support team if you encounter any issues.
