Her communication skills stand out as a major strength, with numerous reviews noting how well she explains complex medical information, test results, and treatment options in terms patients can comprehend. Many patients describe her as knowledgeable, well-prepared, and familiar with their medical histories before appointments.

Patients also share
The reviews contain very few criticisms or areas for improvement. One review gave a 3.23-star rating mentioning they "got really good response as my expectation," which appears positive despite the lower rating. Another 4.04-star review simply noted "the car was on time," which seems unrelated to the provider's care. A single review with a 4.1-star rating used only the word "pleasant" without elaboration. These lower ratings appear to be outliers and do not identify specific concerns or patterns of issues with Diana's care.
