Patients appreciate
Diana Nanayakkara receives overwhelmingly positive feedback from patients who consistently praise her exceptional communication skills, thoroughness, and professional demeanor. Patients repeatedly highlight that she takes time to listen carefully to their concerns, explains medical information in understandable terms, and never makes them feel rushed. Her knowledge and expertise in cardiology are frequently mentioned, with many noting she is well-prepared and familiar with their detailed medical history before appointments. Patients appreciate her warm, caring, and compassionate personality, describing her as friendly, kind, and personable while maintaining professionalism. Many reviews emphasize that she answers all questions thoroughly, provides clear explanations of test results and treatment options, and demonstrates genuine concern for patient wellbeing. Several patients note she goes "above and beyond" in her care and ranks among the best healthcare providers they have encountered.
Patients also share
The reviews contain very few criticisms or areas for improvement. A small number of lower-rated reviews (in the 3-4 star range) offer minimal specific feedback, with most still providing generally positive comments. One patient mentioned the provider was "obviously being rushed" though still provided kind and professional care. A few reviews are brief without detailed commentary, and occasional reviews mention good but not exceptional experiences. However, these represent a tiny fraction of the overall feedback, and even these reviews rarely identify concrete problems or specific areas needing attention.
