"I wanted to discuss contraception and found Dr Flavia at the brasilian consulate website and she was great. Obrigada doutora!"

"Amazing care!"

"I saw Dr Theil in June 2023 for my annual and everything went very well. She listened to my concerns, did a comprehensive examination and I received my results through the portal within 1 week. Recently I had an issue, sent her a msg and she responded within 1 hour, added me to her schedule and tested me, saving a trip to urgent care. Also the office is in a great location and staff is very helpful. "

  • November 12, 2020
"I saw Dr. Theil for more than 5 years but after the last experience I don't intend to return ever again. She gave me incorrect information about an exam and potential lump in my breast. Initially he assumed the error but did not set out to resolve it. In trying to resolve the situation, she refused to respond to my subsequent attempts at contact. The assistant she put in charge was extremely rude and zero professional. In addition to the complications that I will have to resolve regarding the exam itself and the lack of professionalism of the doctor and staff, I can no longer entrust my health to a professional who deliberately hides information from the patient, makes a mistake and does not propose to resolve it. I also feel sorry for the positive reviews I made to the doctor in the past and I feel an obligation to prevent other people from going through this with her."

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.
