"found that the appointment was 30 minutes late, any item brought up in the appointment was immediately dismissed by Dr portnoy, did not want to listen to concerns from patient, the visit was very much focused on what should be and not centered on what is, ordered two tests with one result immediately returned and then a second test within a good time but results not released for up to 3 months later-a notable lack of empathy and concern for patients"

"I regret to say that my experience with Dr. Portnoy was incredibly disappointing. Despite waiting patiently for close to two hours in the room for my appointment, I was met with a deflective apology and a severe lack of bedside manner. Not only did he fail to address the issue I sought help for, but he also provided zero substance or assistance. It’s disheartening to encounter such a lack of professionalism and empathy in a healthcare provider."

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.
